Leonardo's Shadows

Leonardo da Vinci's art theory was compiled by a pupil, Franceso Melzi, in about 1540 into a celebrated Treatise on Painting, which explained perspective and shadows and numerous other techniques of art. It was widely read in later centuries. Digita Vaticana has just released a digitization of one of the manuscripts, Barb.lat.4304. Here is its explanation of the shadows seen on bodies at a distance:

Full background on the work and a comparison of the manuscripts can be found on the Treatise on Painting website at the Institute for Advanced Technology in the Humanities, University of Virginia.

Digita Vaticana has been fairly busy as the Roman summer hots up, issuing a total of 204 items on July 14 and 23. Because of my own holiday in Sweden (more from that later), I am getting in arrears, so I beg pardon that the following list is not fully annotated. There are lots of art gems in this release. Here is a nativity scene from the beautiful Barberini Book of Hours:

Below is the full list of 204 items issued on July 14 and 23. The Digita Vaticana index and catalog server is now frequently out of service (more than 80 hours offline July 23-26), so in the following list, most of the links are to the digitizations themselves, where the servers tend to be more stable.
To finish, here are Moses receiving the Ten Commandments and Noah's Ark from Barb.lat.3984:

Pirates, How to Deal With

A celebrated account of how Julius Caesar was held ransom by pirates has at least two endings. That by Livy maintains Caesar paid the ransom, then went back, seized the pirates and crucified them. The version by Polyaenus has it that Caesar, after borrowing a ransom from Miletus, organized a feast for the pirates:
In high spirits at the large sum they had received, they gave loose to their appetite, and drank freely of the drugged wine, which presently sent them to sleep.  In that state Caesar ordered them to be slain, and he immediately repaid the money to the Milesians.   (Book 8  Chapters 1-25: Romans)
Neither method was employed with the recent wave of piracy on the Somali coast. I leave it to readers to debate how best to deal with pirates. Polyaenus has a series of more than 800 recipes for dealing with all sorts of human pests.

Among the digitizations July 9 at Digita Vaticana is a Greek manuscript of these Strategemata, Barb. gr. 263. For the current state of thinking about Polyaenus, consult a review of recent conference papers on the book, where it is asserted that the most authoritative title of Polyaenus’ work is Strategika, not Stratagemata.  There is an English translation at Attalus.org.

Strange Beasts

The caladrius was an all-white bird, which, when placed on the bed of a sick person, supposedly foretold if they would live or die. If the person were not going to recover, the caladrius looked away from them, but if they were to live, the bird looked directly into their face and drew the sickness into itself.

Medieval bestiaries, of which the digitized Aberdeen Bestiary is a fine example from the 12th century, were based on the Physiologus, an anonymous Greek-language book dating back to perhaps the 2nd century. On June 30, the BAV in Rome digitized and published online a 17th-century Greek manuscript of it, Ott.gr.354. Here is its caladrius giving a bearded man his doom on folio 64r:

All of the images in the Ottoboniani Physiologus are of great interest. Here is one of the sirens, from folio 45r:

This early Christian compendium contains 48 stories about the nature of real and mythical animals, plants and stones. In its mixture of fact and fiction, it is no more reproachable than the infotainment and "science documentaries" with half-truths, portentous voices and dramatic music which air on daytime television.

A Physiologus for TV with similar self-important commentary would be a great satire. Imagine the stock film clips which could be dug up for the elephant (folio 13r), of which we are told it cannot bend its legs, rarely has the desire to mate and practices water birth.

The Physiologus was once as well known as any TV series is today. It was translated into Latin and had enormous influence in the medieval world. Translations and adaptations from the Latin introduced the Physiologus into most languages of western Europe. Its magnificently bogus science shows up in most European literatures including the works of Shakespeare.

Ancient Science

Ancient science was kept alive through the Middle Ages by constant copying and anthologizing. One compilation that has come down to us was gathered at Constantinople at the end of the 13th century and contains the soundest text we possess of the Geography of Ptolemy of Alexandria. His work is one of the greatest scientific achievements of the ancient world.

Here is a Ptolemy diagram from the introductory book, How to Draw a Map of the World, with a simple trig lesson showing how to transfer arcs relative to your standpoint (at left). It's at 129r. One can read the text explaining the concept in part 1.2 of the Berggren-Jones translation at Google Books.

This codex contains Ptolemy's coordinates, but not his world maps. Some of the most exciting research of the past decade has examined the possibility that Ptolemy was hit by a garbage-in-garbage-out situation whereby he unwittingly relied on false experimental data (the earth's circumference), leading to some spectacular failures in his essentially brilliant atlas.

Klaus Geus and Irina Tupikova argued in 2013 that mystery locations on Ptolemy's map are none other than the Gulf of Finland and Poland's Vistula River if one adjusts the false data. We now stand a good chance of identifying all 6,400 places for which Ptolemy gives coordinates in the Geography.

Various other scientific texts by authors as diverse as Euclid and Abu Ma'shar of Baghdad are all bound into the Vatican's massive 397-folio volume. Here is an unidentified diagram from folio 209v.

This codex, which is a kind of album of the best of ancient science, was brought to Rome by Isidoros, (c. 1385 to 1463), metropolitan of Kiev and later a Roman cardinal, and it thus ended up in the Vatican collection of Greek manuscripts as Vat.gr.191. It is one of the treasures that has finally entered our modern album of science, the internet. Digita Vaticana placed it online on June 22.

Renate Burri's description of the codex (in German) can be consulted on Google Books. Burri has argued that the first diagram above is by a Byzantine editor, Manuel Chrysoloras, not by Ptolemy.

Also new in the uploads this week is one of the books that is known as a Barberini Codex, this one being an evangeliary made at one of the two main centres of monasticism on Lake Constance, either Reichenau or St Gallen, just a few years before 1000 CE. Here is its illumination of the Ascension (folio 84v): 

Below is my own list of the 64 new items uploaded June 22, which take the posted total to 2,264. As always, I have compiled this in haste, using web searches to grab keywords, so this is subject to correction. The materials below with the shelfmark Borg. copt. are a variety of biblical and other materials, some of them only single leaves or papyri. For more information about the materials from the Capponi collection, Cozzo's 1897 printed catalog can be consulted at Archive.org.
Two more images from the Barberini Codex show the Three Magi (fol. 18v) and the Presentation at the Temple (fol. 24v)

They Don't Make Hats Like This Any More

All 40 of the additions made on June 16 to Digita Vaticana come from the collection of Marquess Alessandro Gregorio Capponi (1683-1746), which became part of the Vatican Library at his death. Capponi did not collect classical books at all, but left many manuscript documents with a bearing on eighteenth-century Roman life, drawings from the period and archaeological notes.

There is a very old catalogue (Christies sale) and the 1897 catalogue by Cozzo on archive.org, but very little information is attached to the manuscripts online at the BAV, making it hard to browse them. Here is a 17th-century heraldic blazon with a fanciful hat, from Cappon. 51, described in the catalog as a stemma di tipo flammingo: Look closely for the head.

Digita Vaticana seems to be bringing manuscripts online by a series of campaigns on individual collections: the Archcapitular Library of St Peters was first up, and now the Capponi collection is in focus. If you are hanging around for material in the Vat.lat. series, it may be a long wait. Here is the full June 16 list:
Above is a fine little borderless map (Cappon. 56) of the Near East with Damascus, Jerusalem and the Red Sea, which is satisfyingly .... red.

Still to come is one of the most interesting Capponiani items: autograph writings of Machiavelli in Cappon.107, comprising parts of his drafts of his History of Florence and his Letter to Vettori, according to Silvia Ruffo-Fiore. Cappon.52 has been chosen as a fund-raiser item, so consider donating for it:
