A Supermoon, when the full moon is closest to the Earth, blazes like a searchlight in the sky
When the full moon (or the new moon) coincides with the moon's perigee, the closest that it comes to earth in its elliptical orbit, it is known as a "supermoon." It appears larger and brighter than usual, and when it is at its highest point, it blazes like a searchlight in the night sky. In 2019, we have a series of three full moon supermoons in a row, January 21, February 19, and March 21. (A curmudgeon will tell you that the applellation "supermoon" isn't a scientific term, but let's use it anyway.) The January supermoon, spectacularly, was also a total eclipse, turning into a huge, blood-red ball at its height.
The Snow Moon of February
The February supermoon coincided with the Snow Moon. It is called that because February is the month of the greatest snow fall. Some Native American tribes called it the Hunger Moon, because weather made hunting difficult. February does not always even have a full moon, but this year's blinding Supermoon was the brightest of all this season's supermoons. We still have March to look forward to.
The Homeric Hymn XXXII to Selene
Our Quotation of the Month is the Homeric Hymn XXXII to Selene, Goddess of the Moon. The Homeric Hymns, approximately from the time of Homer (ca. 750 B.C.) are all anonymous, but our unknown bard may have had a supermoon in mind when he described the brilliant radiance of the moon as Selene, in her chariot drawn by a team of "arch-necked shining" steeds, courses across the sky.
Selene (Roman Luna), sister of Helios, the Sun, was often identified with Artemis, just as Helios was often identified with Apollo. Helios and Selene, however, are not so much mythological figures as personifications of Sun and Moon. Yet there are stories about Selene, one of which is included in the Hymn. As with many other maidens, willing and unwilling, Zeus had sex with Selene and she had a child by him, the beautiful Pandia ("All goddess").
Selene and Endymion
However, Selene was not always the victim; sometimes she is depicted as the aggressor. There are many versions of the story, but the basic idea is that she fell in love with a beautiful young man named Endymion. In some versions he is a shepherd, in others a hunter, a king, or even an astronomer who liked to study the moon. At the request of Selene, Zeus made him immortal and forever young by putting him in perpetual sleep (in some versions, Endymion himself made the request). Selene visits him every night, and she is supposed to have had fifty daughters by him. (The mechanics of this arrangement are unclear!)
Below, in Greek and English, is the bard's celebration of the radiant lady of the night. Note that in the first line of the poem, the poet uses another word for "moon," Mênê. As we see in other Homeric Hymns, the final lines lead directly to another song; this practice leads scholars to believe that these short poems were intended as preludes to longer songs.
Endymion, asleep, with his dog. Here he is depicted as a hunter. Relief in the Capitoline Museum, Rome. From Roscher, Ausführliches Lexikon der Griechischen und Römischen Mythologie, 1884. The dog seems be trying to wake his master up!

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.

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.
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.

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:
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.

Read about the 1845 Eureka Machine for Composing Hexameter Latin Verse
Another Victorian machine which could be called an early special-purpose
computer was the Eureka machine designed by John Clark in 1845 for automatically
composing Latin hexameter poetry. It still survives, in a museum in Somerset,
England. Click here to read about it.
Book: Traditional Themes and the Homeric Hymns
The book, out of print for a while, is again available by "on-demand" production. Contact the publisher for information.
New selections are available on this Web site for free reading. You can read Chapters 1 ("Introduction") and 10 ("Conclusion: the Place of the Hymns in the Ancient Greek Oral Tradition"), Appendix I ("Outlines of Themes Identified in the Hymns"). You can also see diagrams of the themes as they appear in the Hymns.
Article: "Thought Clusters in Early Greek Oral Poetry"
An article, by Cora Angier Sowa and John Sowa, describes in detail the quantitative and mathematical methods used on the computer to identify thematic elements in Hesiod and the Homeric Hymns. Material from this study was later integrated into into the more comprehensive Traditional Themes and the Homeric Hymns. Click on "Thought Clusters in Early Greek Oral Poetry". 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.
In orally composed poetry like Homer's Iliad and Odyssey, and Hesiod's Theogony and Works and Days, there was no written text (the alphabet being barely known at the time, around 750 B.C.). The bard, like a jazz musician, recomposed his story each time (to a melody now lost to us), using stock phrases or "formulas" and repeated scenes. Since the story was enjoyed not by reading but by hearing it, there were no punctuation marks or chapter headings to tell listeners where they were in the narrative or its episodes. The skilled singer used, instead, repeated words and phrases to serve as "oral punctuation" to articulate the story and provide emphasis for important themes and concepts.
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.
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.
"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!

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.

Nationale de France, Paris.)
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.
