Articles:

Indic-Siamese Bitexts and Ayutthaya Scribal Culture: Exposition and Exegesis in Three Kham Luang Manuscripts

Tossaphon Sripum, Trent Walker

Through an analysis of the intricate layouts, scripts, and color-coding of three bilingual Thai Buddhist manuscripts, this study reveals how these distinct scribal choices were deployed strategically to distinguish exposition from exegesis and to map the structure of court poetry in visual terms.

“These Lots Never Deceive”: Compiling and Reading the Latin Manuscripts of the Sortes sanctorum

Bruno Schalekamp

By exploring the intricate compilation and reception history of the popular late-antique dice divination text known as the Sortes sanctorum (“lots of the saints”), this article details how the work could serve as a useful pastoral and secular tool for navigating fraught decisions in everyday life.

Of Catalogs, Cupboards, and Chemists: Revising the Handlist of the Ordinal of Alchemy

Lisa H. Cooper

This paper untangles a century of bibliographic misunderstandings and cataloging oversights that have obscured the material history of Thomas Norton’s 1477 Middle English poem, the Ordinal of Alchemy. It includes a newly revised handlist of forty-eight known witnesses of the text.

Adventures in the Animal Archive: New Techniques for the Genetic Analysis of Parchment Manuscripts

Timothy L. Stinson, Melissa K. R. Scheible, Rachael Thomas, Nicholas E. Wagner, Matthew Breen, Benjamin J. Callahan, Kelly Meiklejohn

This piece summarizes an interdisciplinary study that deployed a new and entirely non-destructive brush procedure to extract animal DNA from ninety-one historical manuscripts held at Duke University. The project report shows how parchment can serve as a repository of biological data concerning medieval agricultural history, livestock economies, and trade routes.

Coffee With A Codex is an informal lunch or coffee time to meet virtually with Kislak curators and talk about one of the manuscripts from Penn's collections. Each week we'll feature a different manuscript and the expertise of one of our curators. Everyone is welcome to attend.

On July 2, curator Dot Porter will bring out LJS 386, substantial sections from an illustrated treatise on the measurement of weight, with a historical introduction to theories of gravity and weighing in Greek and Arabic science; tables of densities of substances including metals, precious stones, solids, and liquids; and descriptions of different types of balances. Undated, but likely copied sometime in the late 13th or early 14th century.

Here we have the first part of a four-part poem in octaves on the monarchy of Portugal, with allusions to astrology, alchemy, and cabala. It's an interesting book that while written by hand reflects the publishing history of the printed test. The manuscript contains a copy of the edition printed in Lisbon in 1624 in 131 octaves, with its accompanying annotations on selected octaves, followed by another copy of the work, copied from an edition printed in Hamburg in 1644 in 133 octaves; 20 aphorisms of Bocarro from 1626; summaries of 3 documents (dated 1659, 1640, and 1668) related to Manoel Bocarro; and a list of dias aziagos (fateful days) for a particular year, date not given. The list of fateful days is probably from another manuscript, being written in different hand. (UPenn Ms. Codex 1646)

Here is Ms. Codex 1566, a 14th century book of hours from Metz, France: a brief look inside, at the calendar, and then a miniature of the Virgin and Child, nursing - typical of use of Metz - at the opening of Matins.

On June 25, curator Dot Porter will bring out Ms. Codex 1564, a copy of the Penitential Psalms in French, written in France in the 17th century. It is written in a lovely calligraphic script and contains many illustrations. It's bound in a gorgeous embroidered binding, which we'll spend some time looking at, too.

Sooo I was out of town last week and neglected to queue up social media posts before I left, so in apology for the lack of content I share with you our most recent acquisition: an artist's facsimile of Rosenbach MS 1004/29, a 15th century medical almanac. The original manuscript includes several pages of moon phase charts, a urine wheel, and a bloodletting guide - everything a 15th century medical practitioner would need! The facsimile was made by Bryn Michelson-Ziegler, an artist local to Philadelphia who also works at the Rosenbach Museum and Library. Check out Bryn's website here and her Insta here!

A "bat book" is a specific kind of book, where the pages fold out into full sheets. Bryn played with the term, by creating a leather binding in the outline of a bat with outstretched wings (the binding of the original only partially survives, but it was definitely not in the shape of a bat). We are thrilled to be adding this book to our collection!

If you want to learn more about the original, you can see digital images and read the catalog record here, or you can watch the recording of the Coffee With A Codex that I did with Rosenbach Librarian Elizabeth Fuller.

A couple of weird little guys are chilling out in the bottom margin of Ms. Codex 724 f. 326v, a 13th century illuminated Bible.

On June 4, curator Dot Porter will bring out Ms. Codex 2141, a 16th century collection of approximately 20 prayers with calligraphic ornamentation, including prayers for the morning, forgiveness of sins, comfort and help, the sermon, receiving the Eucharist, and the evening meal; and to the Holy Trinity. Probably written in Nuremberg, Germany, no later than 1579.

On May 28 curator Dot Porter will bring out Ms. Codex 869, a collection of treatises, bullae, and regulations of Franciscan interest, including works of Saint Augustine, Saint Bonaventure, and Saint Bernard and bullae of Eugene IV and Nicholas IV. Written in Italy between 1460 and 1510. We looked at this one on April 30 and only scratched the surface, so we are going in again for a deeper dive.

If you want to watch our first visit with this manuscript, you can see it here:

Although this page has several illuminations identified as Saint John, the animal in the top margin appears to be a ram. It's definitely not an eagle (which is the animal that John is associated with). The book is Ms. Codex 724 f. 326v, a 13th century illuminated Bible.

By popular demand (it's us, we're demanding!), here is the inside view of LJS 361, a 14th century manuscript in its original binding, written in Italy. The manuscript contains the opening and closing sections of astronomical and astrological tables on either side of a remnant of commentaries on gospel and epistle readings.
