WELCOME TO MINERVA SYSTEMS

Welcome to Minerva Systems, an enterprise created by Dr. Cora Angier Sowa. It is a product of the author's longtime search for connections between the aesthetic and the technological. It is also devoted to examining the continuity of influence of Greek and Roman Classical civilization, and to exploring how ancient insights can be applied to today's world. This site presents a selection of writings and photography by the author on some interconnected topics: Classical literature, computers and humanities, railroads and engineering, architecture, music, and movies, and the aesthetic appreciation of the marvels of the built environment.

Athena - the Roman Minerva - was goddess of both intellectual wisdom and technical crafts. Accompanied by her owl, she was also protector of the city of Athens.

FOR MY CLASSICAL READERS! A NEW ITEM! REPORT ON THE AMERICAN PHILOLOGICAL ASSOCIATION'S 1969 SUMMER INSTITUTE IN COMPUTER APPLICATIONS TO CLASSICAL STUDIES Click to read the report: HTML: "Summer Institute 1969" PDF: "Summer Institute 1969 PDF" PDF (Searchable): "Summer Institute 1969 Searchable PDF" The final report to the National Endowment for the Humanities of the APA (now SCS) Summer Institute in Computer Applications to Classical Studies, held at the University of Illinois at Urbana-Champaign in 1969, and in which I was a participant, has now been put on this web site. This was a seminal experience in the development of digital methods in the Classics, starting with simply putting as much Greek and Latin literature in digital form as we could (mostly on IBM punched cards! I personally punched the texts of the complete Homeric Hymns and Hesiod's Theogony and Works and Days, all in capital letters and with no accents, because that's all the punched cards could record). The participants in the Summer Institute varied widely in experience and interests, and visiting lecturers were equally varied. Introduction was made to programming languages that were important at the time (FORTRAN, PL/I, SNOBOL), and to statistics, linguistics, and various concepts for deriving information from and about the digitized texts. And yes, we watched the moon landing on July 20, 1969, sitting with the rest of the university community on the floor of the UIUC gymnasium, watching on the big screen as the Eagle landed and Neil Armstrong became the first human to walk on the Moon. The report on the Summer Institute can be read THREE ways, either in .html or in two .pdf formats. The first PDF version is an actual image of the original report. The second is a cleaned-up version that is easier to read, and is also searchable. It was very kindly prepared by John Muccigrosso, Chair and Professor of Classics at Drew University, Madison, NJ.

FOR MY RAILFAN READERS! CORA SOWA'S RIGHT-OF-WAY ("Railroad History of Cora Angier Sowa")

While my professional career is in Greek and Latin Classics and in computers (interests that I combine in the field of digital humanities), I am also a lifelong railfan. I grew up in a house above the old Los Angeles Subway tunnel and trainyards, my father was Head Cost Analyst for the Los Angeles Division of the Southern Pacific, and my grandfather and uncle were civil engineers specializing in railway and highway bridges. I now live in Croton-on-Hudson, New York, overlooking the Hudson River and the historic tracks of the former New York Central, now CSX, Metro North and Amtrak. On the series of Web pages called "Cora Sowa's Right-of-Way: Railroad History of Cora Angier Sowa,", I display some of my collection of rail photos, with commentary about them. Pages called "Engineers (Civil, Electrical, and Mechanical) in the Family," add more archival material about various family members' contributions to the history of railroads and engineering.

Click HERE for "Cora Sowa's Right-of-Way." Click HERE to read "Engineers in the Family."

THE RIGHT-OF-WAY The right-of-way, the stretch of land on which the tracks are laid, is the universe of the train. It is an alternative reality, intersecting but distinct from our usual world of streets and roads. You can go on it if you are on a train, or if you work there, or if you, unseen, trespass. Whether it is the narrow branch or spur disappearing mysteriously between buildings or merging into fields and forests, or the long, straight tangent of the main line, it speaks of something magical, just out of sight. It is the stage, on which an awaited drama will be acted out. It is a space warp, a pointer leading to a place of possibility. An invitation.

CLASSICAL QUOTATION OF THE MONTH Preserving the past, inspiring the future

Every month there will be a new classical quotation in this space, appropriate to the season or to current events. Usually the quotations are from ancient Greek or Latin, with occasional forays into other sources, such as mediaeval Latin or ancient Near Eastern literatures. Previous quotations (beginning in September, 2004) are archived in "Archived Quotations of the Month" for each separate year. An index to all quotations for all years is located in the first Archived Quotations page. Translations are my own, except where otherwise noted. Do you have a suggestion for a future Quotation of the Month? If so, send me your suggestions at casowa@aol.com.

Frogs in my garden

Brekekekex koax koax!

Throughout August, a night chorus of tree frogs has carried on a constant conversation. And they are LOUD. They drown out almost everything else. (Although now the crickets are starting to mount a countersong.)

A chorus of frogs, did you say? There is only one possible Quotation of the Month, and that is the frog chorus from Aristophanes' Frogs, who annoy Dionysos so much on his journey to the Underworld.

Athens in a time of exhaustion needed a lift

Aristophanes' play The Frogs (Greek: Batrachoi) won first prize at the Lenaia, one of the festivals of Dionysos, in January 405 B.C. It was a time of disillusionment and exhaustion at Athens. The Peloponnesian War, which had been going on for more than thirty years, was dragging to its conclusion (in which the Spartans would ultimately prevail). The Athenian fleet had just won the naval battle of Arginusae, but a bitter taste was left by the prosecution of the generals in charge, for neglecting to save sailors on the floating wrecks. A few years before, in 411 B.C., democracy itself was temporarily overturned by the oligarchic party of The 400. The great political leaders of an earlier time were gone, men like Pericles, dead of the great plague of 430-429 B.C., which itself had sapped the morale of the Athenian people.

The great Athenian dramatists were also gone. Aeschylus, whose grand plays like the Oresteia trilogy make him the father of classical Athenian tragedy, had died fifty years before, in 456 B.C. Euripides, who had introduced a quality of emotion and human feelings into plays like The Trojan Women, had died just recently, in 406 B.C. (Sophocles, the third great master of tragedy, would die during the preparation of The Frogs for production.) Where could the Athenians look for inspiration and moral courage?

Dionysos visits the Underworld so that he can bring back Euripides

The god Dionysos, having fallen totally in love with Euripides and his plays, decides to go to the Underworld to bring back his beloved playwright. He and his slave Xanthias first visit his half-brother, the hero Heracles, to ask his advice on the best way to get to the realm of Hades, since Heracles went there himself to bring back the three-headed dog Cerberus. Heracles first suggests various ways of committing suicide, but then tells them a better if more difficult way. So then we see Dionysos, improbably dressed as Heracles, and Xanthias, on the shore of a lake. There they hire Charon, who is ferrying a corpse, to take them across. They also make a deal with the corpse to carry their baggage. Charon, however, will not take the slave, Xanthias, who has to walk around the lake. He will only take Dionysos, who has to help row the boat, unathletic as he is, despite the Heracles getup.

A chorus of spirit frogs

It is on the Acherusian Lake that we encounter the Frogs who give the play its name. Charon assures Dionysos that he will hear "the loveliest songs" — of "frog-swans." Dionysos gets a rude shock, hearing the very loud croaking of assertive amphibians. The frogs are actually ghosts of frogs who died, who formerly inhabited the reedy marshlands. They sing, er, croak nostalgically about their old lives. Just as Odysseus saw Orion, the great hunter, still vigorously hunting game in the afterlife, so the frogs still dive among the water plants and sing their loud "Brekekex koax koax!" But it infuriates Dionysos, who is already suffering from blisters on his hands and backside from rowing. If he leans too far forward, he says, his arse will soon yell "Brekekekex koax koax!"

Finally Dionysos and Xanthias get to the other side, and we see no more of the frogs. Dionysos encounters the main chorus of the play, made up of Eleusinian initiates, who also pursue their rites in the Underworld. Meanwhile, a contest has broken out between the two deceased dramatists Aeschylus and Euripides, as to whose plays are better. The winner will be invited to sit at Pluto's side at dinner in the assembly hall. (Sophocles, recently died, politely defers to Aeschylus.) Aeacus, one of the three mythic judges in the Underworld (the others are Rhadamanthus and Minos) decrees that they will bring out a set of scales, in which the "weightiness" of each contestant's poetry will be determined. Dionysos, as god of drama, will be the judge.

Surprise! Aeschylus wins the contest against Euripides

Aeschylus and Euripides takes turns reciting lines from their dramas, often interrupting each other with silly remarks and criticisms of each others' styles. Dionysus is asked to make his choice, and he gives his opinion that the poet chosen to return to the land of the living should not only be the best dramatist, but the man who can best advise the city on political and moral questions which trouble it. Finally he says "This is my decision; I shall choose the one my soul delights in" but when Euripides reminds him of his oath to take him, not Aeschylus, home with him, Dionysos replies "It was my tongue that swore — but I choose Aeschylus!" (vv. 1466-1471). This line parodies a famous quote from Euripides' Hippolytus in which Hippolytus has sworn not to tell his father Theseus of his stepmother Phaedra's illicit love for him "My tongue swore, not my mind."

Aeschylus, by Dionysus' choice, will return to the land of the living for a time, in order to save Athens by his noble counsel. He, in turn, chooses Sophocles, not Euripides, to hold his place in Hades while he is gone.

This final scene, like the entire play, is full of political and topical comedy bits that would instantly strike a chord in Aristophanes' Athenian audience.

Quotation of the Month, Arisophanes' Frogs vv. 209-249

For our Classical Quotation of the Month, we bring you, in Greek and English, the opening verses of the Frogs' chorus. The text is from the Loeb edition of 1924. The translation is my own.

Brekekekex koax koax!

Aristophanes Frogs 209-249

The frogs describe their bubbly song-filled life FROGS: Brekekekex koax koax, brekekekex koax koax. Marsh-born children of the springs, let us give voice to our combined shout of hymns our sweet-sounding song, koax koax, which, in praise of Nysaean Dionysos son of Zeus, we used to shout in the Marshland when the drunken merry-making crowd of populace at the festival of the sacred Pitchers entered our precinct. Brekekekex koax koax. DIONYSOS: Well, I am beginning to feel sore in my rump, o koax koax. But perhaps you don't care. FROGS: Brekekekex koax koax. DIONYSOS: May you and your "koax" perish. There's nothing here but "koax." FROGS: Well said, busybody. The Muses well-skilled in the lyre love us as does horn-footed Pan, who plays music on the pipes. Apollo the lyre player rejoices in us besides, on account of the reed, the lyre's cross brace, which we grow in the waters of the marsh. Brekekekex koax koax. DIONYSOS: Well I have blisters and my butt has been sweltering for a long time; if I lean forward it will soon say "brekekekex koax koax." So, o song-loving tribe, just stop. FROGS: Rather, then, we will sing out, if ever on beautiful sunny days we sprang through the sedge and reeds, delighting in the oft-diving melodies, or when fleeing Zeus's watery storm we gave voice in the depths to our nimble choral dance with bubbles splattering all around. . . .

One of our tree frogs, who somehow got into our upstairs hallway. It may have hatched over the winter in one of our flowerpots. I caught it in a jar, photographed it, and released it into the garden. (Photograph by C.A. Sowa, Feb. 24, 2016.)

MINERVA participation in the Chicago Colloquia on Digital Humanities

CHICAGO COLLOQUIA ON DIGITAL HUMANITIES AND COMPUTER SCIENCE

Since their inception in the fall of 2006, I have been attending the Chicago Colloquia on Digital Humanities and Computer Science (DHCS), held at a rotating group of universities around Chicago. These Colloquia now draw participants from all over the world, who present projects covering many fields, including such interests as visual arts, archaeological reconstruction, musical composition, literary criticism, social trends, popular culture, history, and many fields yet to be discovered. Of the projects I have submitted under the name of Minerva Systems, a couple have been presented as poster exhibits. Others I have informally circulated among the participants. But whether one is presenting a paper or simply taking part in discussions, the Colloquia offer an opportunity to exchange a wealth of ideas. Workshops and smaller discussion groups, too, are well worth while.

For information about the Colloquia, visit the DHCS Web site at "http://chicagocolloquium.org". Information about all previous Colloquia (2006, 2007, 2008, 2009, 2010, 2011) can also be accessed from there.

Previous DHCS Colloquia and MINERVA offerings: Click on the buttons on the right to read the MINERVA presentations. 2006 The theme of the first Colloquium (2006)was "What to do with a Million books," posing the problem that, now that all the world's libraries have been put in digital form, what do we do with them? MINERVA Systems presented a demonstration showing the capabilities of MINERVA as a set of tools for carrying out a project to study a work of literature, using digital methods. The first Colloqium was held at the University of Chicago at its Hyde Park Campus. 2007 The emphasis of the second Colloquium (2007) was on using digital materials in a collaborative environment, and on discerning what studies are better undertaken by using digitized versions of materials such as images and text than by using the original non-digitized sources. The MINERVA demonstration for 2007 highlighted new additions to the Systems Analysis Tutorial/Project Planner, which aid the user in steps to planning and carrying out a project in an organized way. These techniques are adapted from the commercial and scientific fields, where teams of persons who may be working in distant locations must coordinate their efforts. The second Colloqium was held at Northwestern University in Evanston, Illinois. 2008 The theme of the third Colloquium (2008) was "'Making Sense'- an exploration of how meaning is created and apprehended at the transition of the digital and the analog." "Sense-making" is a field concerned with finding meaning in vaguely defined material. As usual, this third Colloquium brought together a terrific group of diverse scholars and students working in different areas of computer applications. These included not only literary and sociological studies, but such inventive applications as a study of different musical genres (country, gospel, blues, hip hop, heavy metal, etc.) to see which body parts (head, heart, hand, etc.) are mentioned most often, and three-dimensional recreations of archaeological and historic sites, including a study of pedestrian traffic patterns in an ancient Turkish town destroyed by Cyrus the Great. Minerva Systems submitted a paper to the third Colloquium, "A Bridge Across the Culture Gap: Build Your Own Project Using the Minerva System for Study of Literary Texts", which was given as a handout to all who were interested. Additions to the MINERVA System emphasized the need to serve "the great unserved middle," between the Luddites and the Rocket Scientists, of scholars and students, who would like to be introduced to elements of logical analysis and computerized methods. The third Colloqium was held at the University of Chicago. 2009 The theme of the fourth Colloquium (2009) was "Critical Computing", seeking to explore how productive research collaborations between computer scientists and humanists can be most effective. How might computation provide new critical tools for humanists? How might humanists help us understand the real meaning and import of computational results? The fourth Colloquium was held at the Illinois Institute of Technology. 2010 The theme of the fifth Colloquium (2010) was "Working with Digital Data: Collaborate, Curate, Analyze, Annotate." Emphasized in particular were papers or poster sessions about annotation, scholarly crowdsourcing, and challenges of human/computer interaction. How to create better texts from OCR may be a problem in which new forms of human/computer interaction hold particular promise. Minerva Systems circulated a paper titled "BUILD-A-BEAR" RESEARCH PLANNING: CLARIFICATION OF DEFINITIONS AS THE KEY TO CHOOSING OR WRITING PROGRAMS, a discussion of analytical methods designed to help the scholar/user analyze his or her own research problems sufficiently to choose or design an appropriate computer solution. The fifth Colloquium was held at Northwestern University. 2011 The sixth Colloqium (2011) was held at Loyola University at its Water Tower Campus. Minerva Systems was again in attendance. 2012 The seventh DHCS Colloquium was held at the University of Chicago at its Hyde Park campus. Minerva attended. 2013 The eighth Colloquium, attended by Minerva, was held at De Paul University, near Lincoln Park.

The Reliance Building, at State and Washington Streets in Chicago, January, 2008. (Photo by C.A. Sowa.) The Reliance Building, like the MINERVA System, was built on principles of modularity and extensibility.

The Reliance Building, an incredible little jewel in the middle of Chicago's Loop, was not all built at once. When the developer acquired the site in 1882, it was occupied by a five-story building. The leases on the lower two floors expired in 1890, those on the top three in 1894. So, as the first leases expired, the architects Daniel H. Burnham and John Wellborn Root demolished the first two floors, and, jacking up the top three storeys, replaced the demolished floors with the first two floors of the new building. When the remaining leases expired, the top floors of the old building were demolished, and replaced with new floors, designed by Charles Atwood, Root having died. The number of floors eventually grew to fifteen, made of identical structural modules and clad in graceful terracotta, giving the building the perfect proportions that it has today, somewhat overwhelmed, unfortunately, by the gigantism of the surrounding modern buildings.

Today, the Reliance Building, after years of neglect (shabby but still showing her noble "bones"), has been reborn as a boutique hotel, called the Burnham, with an excellent restaurant, the Atwood, on its ground floor, the names being chosen as an homage to its architects.

THE MINERVA SYSTEM FOR STUDY OF LITERARY TEXTS, INTRODUCED A IN SELF-STUDY CD The Loom of Minerva: An Introduction to Computer Projects for the Literary Scholar

The Loom of Minerva is a self-study CD that introduces the Minerva System for Study of Literary Texts, which is a set of tools, some automated and some semi-automated, for planning and carrying out a project in literary study. The Loom of Minerva contains both text chapters and a set of programs. The first chapter, "A Guide to the Labyrinth" (now much revised), can be read on this Web site, and images of two (earlier) demonstrations of the system from 2006 and 2007 can also be seen. More revisions are to come, including an on-line version. Illustrations: Statue of Minerva, Helsinki, Finland (photo by J.F. Sowa); "Palace of Minos," Knossos, Crete, the building that was perhaps the original Labyrinth (photo by C.A. Sowa).

Read about it!

My thanks to all those who have reviewed and used my self-study CD course on using computers and quantitative methods in the study of literature, The Loom of Minerva: An Introduction to Computer Projects for the Literary Scholar, and my thanks to those who continue to give me comments.

You can read Chapter 1, "A Guide to the Labyrinth: The Problem and Its Solution" on this Web site. (Note: this chapter now describes a greater variety of ways to structure a project, e.g., top-down, bottom-up, etc. It will continue to be revised.) You can also see images from two demonstrations of the MINERVA System, from 2006 (emphasizing individual applications programs), given at the First Chicago Colloquium on Digital Humanities at the University of Chicago and 2007 (emphasizing new project planning programs) given at the Second Chicago Colloquium on Digital Humanities at the Northwestern University.

The MINERVA System

The MINERVA System for Study of Literary Texts is a set of tools, some automated, some not automated, for planning and carrying out a project in literary study. Methods of Systems Analysis, borrowed from the scientific and commercial world, are adapted to the study of literature. This methodology emphasizes the use of diagramming techniques and modular design, offering a way to construct a project as a set of units or modules that can be worked on separately and moved around without disturbing the whole. A project is defined as an enterprise that has a goal and an organized way of achieving that goal.

The Loom of Minerva combines the methods of Systems Analysis with the insights of traditional belles-lettres literary criticism. All analysis takes as its point of departure the value of the piece of literature itself to the critic and the reader, as well as the historic, social, or aesthetic qualities attached to it. These alone confer significance on any work of scholarship. Examples grow directly from study of various works of literature, from Vergil to Coleridge to Baudelaire to Victor Hugo to Edna St. Vincent Millay and Gertrude Stein, and works of criticism from Sainte-Beuve to Swinburne to Gertrude Stein (criticizing her own work).

Emphasis is placed on analyzing the language of criticism itself, analyzing exactly what we mean by such terms as "beautiful," "ugly," "pompous," "like a spring garden," etc. By defining our terms with an exactness that can be quantified, we learn to give precision to our thoughts, whether using a computer or not.

What is in The Loom of Minerva

The CD contains both a set of narrative chapters and a set of programs, called the MINERVA System for Study of Literary Texts. The narrative chapters explain and amplify the programs, and the programs illustrate the chapters. The programs are provided in both executable form and source code, to satisfy both non-programmer scholars and programmers who want to play with the code.

• The programs.

  The programs are in two groups, The Tutorial in Systems Analysis and the MINERVA Program Suite. The Tutorial in Systems Analysis takes the student through the steps to plan and design a project, beginning with the Selection of a Topic, going through the activities of drawing hierarchical and flow charts, and continuing to the final Evaluation of Results. The screens are interactive, so that the student can practice designing his or her own project.

  The MINERVA Program Suite is an interactive suite of programs designed for use by scholars and critics of literature. These programs, which can be used with texts of English, Classical, or other literatures, currently contains sixteen programs: eight to perform different types of literary analysis, and eight "OwlData" programs that the scholar can use to create or adapt data for the analytical programs. Currently available are programs to make concordances, search for words and cooccurring words, do statistical studies, perform cluster analysis, and compose original paragraphs. Developed in modular fashion, MINERVA is intended to be expandable, so that in the future more modules can be added to do more things. The latest to be developed is a program to perform cluster analysis based on the program described in Sowa and Sowa "Thought Clusters in Early Greek Oral Poetry."

• The narrative chapters

  The narrative chapters can be read like a book, or they can be entered directly from the programs by clicking on links on the screens.

  The first four text chapters of The Loom of Minerva introduce the MINERVA System. They demonstrate the steps for planning and developing a project, and provide many literary examples for using the programs. Historical chapters of The Loom of Minerva analyze projects past and present, that have used computers and other mechanical devices in the study of literature (including the Eureka Machine for composing Latin hexameters). Also described are works of literature that were inspired by machines, like the short story "Moxon's Master" by Ambrose Bierce (1842-1914), in which a chess-playing robot murders its inventor. Four final chapters of the book are for techies only: a programming manual of Visual Basic, using literary examples, for those gung-ho readers who want to understand the arcana behind the MINERVA programs included with the book.

MINERVA stands for Model INteractive Engine for Recognizing Verbal Artifice.

Advantages of the MINERVA System

The MINERVA programs do not require the use of data that is in a proprietary format. They use plain ASCII text, such as that downloaded from the Internet. The OwlData programs can be used to put downloaded or scanned text in the correct format for the MINERVA programs. The mathematics and statistics used are fairly elementary, such as can be understood as an introduction to basic concepts of what the computer and quantified methods can do. The programs are open-source, as they are intended to be extensible.

A VICTORIAN COMPUTER LIVES AGAIN! WATCH A REPLICA OF CHARLES BABBAGE'S ENGINE IN ACTION

Charles Babbage's Difference Engine and Analytical Engine

Charles Babbage, prolific Victorian inventor, is most famous for two of his inventions, the Difference Engine (1812) and the Analytical Engine (1833), which are perhaps the truest forerunners of the modern computer. The Difference Engine, a mechanical device of rotating gears, was designed to automatically generate mathemetical tables. It was called the Difference Engine because it was based on the principle of computing the differences between successive values of an expression, then the difference between the differences. Versions of the Difference Engine were eventually built and used, but Babbage himself dropped work on it to pursue his real dream, the Analytical Engine. The Analytical Engine was, or would have been, the first "real" computer, capable of performing any kind of mathematical operation, and able to be "programmed," that is, to perform a sequence of operations without human intervention, and to choose, when necessary, between alternative paths of action. It was to be powered by steam, and programs were to be entered into the machine by means of punched cards, an idea borrowed from the then-new Jacquard power looms. Babbage, sad to say, was never able to complete the Analytical Engine.

Ada, Lady Lovelace, "the world's first programmer"

Babbage's collaborator on his Engines was one of history's most remarkable women, Ada, Lady Lovelace, daughter of the poet Lord Byron. These lines from Childe Harold's Pilgrimage are thought to be addressed to her:

Is thy face like thy mother's, my fair child, Ada, sole daughter of my house and heart? When last I saw thy young blue eyes they smiled And then we parted,--not as now we part, But with a hope...

A gifted mathematician in her own right, Ada worked with Babbage until her untimely death in 1852 at the age of 36. In 1842, the Italian engineer Luigi F. Menabrea published a description, in French, of Babbage's Analytical Engine. Lady Lovelace translated Menabrea's article into English, expanding it with commentary so extensive that her "Notes upon the Memoir" are virtually an original work. She provides detailed directions for using the machine to calculate answers to mathematical problems, leading modern writers to call her "the world's first programmer." Her words relate computing to other artistic endeavors:

We may say most aptly that [Babbage's] Analytical Engine weaves algebraical patterns just as the Jacquard-loom weaves flowers and leaves.

A Babbage Engine in London and California

In 1985, the Science Museum in London set out to build a working Difference Engine No. 2, based on Babbage's original designs. It was completed in 2002, and is on public display at the Science Museum. An identical Engine, completed in 2008, is presently on loan to the Computer History Museum, Mountain View, California, where it is on display until May, 2009. Read more about this recreated machine at the Computer History Museum Web site.

A version of the CLUMP cluster analysis program used to identify thematic repetitions is now also being integrated into the MINERVA suite of programs in the self-study CD The Loom of Minerva.

"Verbal Patterns in Hesiod's Theogony"

Reissued here is my article Verbal Patterns in Hesiod's Theogony, which explores the use of verbal repetition in Hesiod's tale of the origins of the gods.

The Eureka Machine for Composing Hexameter Latin Verses (1845)

We think of computers as being very modern, although calculating machines and computer-like devices have been around for a long time. In particular, we think of using such a machine to do such non-scientific tasks as composing poetry as a modern concept. But in 1845, John Clark built the Eureka Machine for Composing Hexameter Latin Verse. It still exists in a museum in England. Read about the Eureka Machine and read the original description of it from the Illustrated London News of July, 1845.

There is more about early computers and their mechanical ancestors in the self-study CD The Loom of Minerva: An Introduction to Computer Projects for the Literary Scholar, described above.

Ships named Minerva

Classically named ships have a long tradition. Illustration: "The PHOENIX and the ROSE, engaged by the ENEMY'S FIRE SHIPS & GALLEYS, on the 16th Augt 1776. Engraved from the Original Picture by D. Serres, from a Sketch of Sir James Wallace's." Lithograph by G. Hayward for D.T. Valentine's Manual 1776.

"Minerva" has long been a popular name for ships. There are cruise ships named "Minerva," including Greek vessels whose owners chose that name as a synonym for their own city patroness Athena. Warships named "Minerva" have graced the navies of Europe from the time of Nelson and Napoleon to the present, whether British "Minerva" or French "Minerve."

It is an interesting choice, considering that Athena, with her gift of the olive, defeated Poseidon, lord of the sea, with his gift of the horse, in the contest to be patron deity of Athens. (See the depiction of Athena and Poseidon below.)

The name "Minerva" for a British warship belongs in the splendid tradition of naming vessels after names from Classical history and mythology. Along with names like "Invincible," "Audacious," "Irresistible," "Insolent," "Victory," and "Dreadnought," we find "Gorgon," "Phoenix," "Achilles," "Apollo," "Dryad," "Endymion," "Hector," "Helicon," "Medusa," "Meleager," and, famously, "Arethusa." The most famous ship named for the Sicilian nymph Arethusa was known for her victory over the French "Belle Poulle" in 1778. Training ships for over a century inherited the name, one after the other.

A frigate "Minerva" participated in the Battle of Cape St. Vincent against the navy of Napoleon on February 14, 1797. The marine painter Thomas Buttersworth (the elder) painted a portrait of "Minerva" in 1810, and the "Minerva" Pub in Hull, England (built in 1831) uses the frigate's symbol, the owl, on its sign. Of course, some ships have been named "Athena" and "Poseidon," too; there was a movie about such a ship called The Poseidon Adventure.

There is a further connection between ships and this Minerva Systems site. In the self-study CD The Loom of Minerva (described above), an analysis of Coleridge's The Rime of the Ancient Mariner is used as a case study to demonstrate methods of Systems Analysis and computer techniques.

A feminist note on the gender of ships: Because of the living qualities of ships, I like to refer to a ship as "she" rather than "it." While some may compare a vessel to a woman because of the supposedly capricious nature of both (although there seems nothing wrong with an occasional playful moment), I think that this view overlooks other qualities. Ships, like women, are beautiful, swift, intelligent, and powerful. I am glad to acclaim them as my sisters!

"Attack on Sidon by Commodore Charles Napier." The battle took place in September, 1840. Sir Charles Napier was a lineal descendant of John Napier, inventor of Napierian logarithms, whose mathematical insights led to the invention of the slide rule, itself an ancestor of the modern computer. The ships in the picture are identified along the bottom as H.M.S. "Gorgon" (flag), H.M.S. "Thunderer" (84 guns), Turkish Corvette (20 g.), Austrian frigate "Guerriera," H.M. Brig "Wasp" (16 g.), H.M.S.S. "Stromboli."

Signed vase painting by the Athenian potter/painter Amasis (6th cent. B.C.), depicting Athena and Poseidon. The two figures are labeled ATHENAIA and POSEIDON. The inscription down the middle reads AMASIS MEPOIESEN ("Amasis made me"). Amasis may well have been African. (Illustration from a lithograph by Kaeppelin et Cie., ca. 1840. The actual vase is in the Cabinet des Médailles, Bibliothèque Nationale de France, Paris.)

Myths of landmarks: Pennsylvania Station and Times Square as centers of the universe, the World Trade Center as a Mythic Place

The World Trade Center was a sacred place long before it was blown up by terrorists. Lower Manhattan was the sacred land of the Lenape Indians, who made their community and buried their dead there. The modern World Trade Center, with its iconic double-towered shape (a nation's gateway, a cosmic tuning-fork?) was a symbol to the world of universal aspirations and longings. As a center of communications (with its towering antenna) and of transportation (as a hub of rail transportation) it had the mana or spiritual power of the crossroads, the traditional meeting place watched over by the gods of trade. The WTC is not sacred just because it, along with its inhabitants, was destroyed; it was destroyed because it was sacred. Today, Mercury returns, as the god of communication and of commerce, along with the spirits of all who have lived and died there.

Essays and reviews on building and architecture

Among the selections on this site is the previously published "Holy Places", a study of myths of landmarks. In addition, there is an epilogue to that essay, on "The World Trade Center as a Mythic Place". This piece continues the author's interest in relating ancient ideas to things that we care about in the modern world.

You can also read two of the author's previously published book reviews on architecture, on Alison Sky and Michelle Stone's Unbuilt America and Albert Mehrabian's Public Places and Private Spaces.

About the Author

The author is an aficionado of many kinds of transportation, including railroads, ships, and airplanes. Here I am "at the wheel" of the ferryboat Eureka (rebuilt in 1923 from the 1890 freight-car ferry Ukiah) at the San Francisco Maritime National Historical Park.
