The soldier who outlived six emperors

A Sahidic Coptic parchment fragment containing the Passion of St. Eusignios — a Roman soldier-saint who served sixty years across six imperial reigns, witnessed Constantine's Chi-Rho vision, and was beheaded at roughly 110 years old by Julian the Apostate — has been digitized by the Vatican Apostolic Library (DigiVatLib, Week 25, June 2026).

A Coptic parchment from an Egyptian monastery tells a story both Christians and Muslims know

A 9th–11th-century Sahidic Coptic hagiographic fragment — five parchment leaves telling the legend of the Seven Sleepers of Ephesus — was digitized by the Vatican Apostolic Library on June 21, 2026, as part of a batch of 22 Borg.copt.109 manuscripts. The fragment, gathered from Egypt's White Monastery by Cardinal Stefano Borgia's missionaries in the 18th century, carries a legend shared by both Christian tradition and the Quran (Sura 18, verses 9–26). First published in scholarly form by Ignazio Guidi in 1887, it is now freely viewable at DigiVatLib.

Copies of ancient Rome, now open at the Vatican

A 17th-century Italian drawing book by the scribe Diogenis Arcangeli — filled with ink and wash copies of ancient Roman paintings, sculptural reliefs, Hadrian's Villa, Hagia Sophia, early Christian apse mosaics, and a Simone Martini-connected folio — has been digitized by the Vatican Apostolic Library and is now freely accessible online. The article introduces the manuscript's 221 IIIF canvases, its place in the Barberini Latino collection, a sister manuscript pointing to a larger antiquarian project, and the grim art-historical footnote that shadows the scribe's surname.

The other earth: a 17th-century counter-earth treatise opens at the Vatican

Giovanni Donato Ferrari's Antichthon Pythagoreae (Barb.lat.2119) — a short 17th-century Latin treatise arguing for the ancient Pythagorean concept of a "counter-earth" hidden on the far side of the cosmos — has been digitized by the Vatican Apostolic Library as part of its Week 22, 2026 release. The article traces the idea from Philolaus of Croton (c. 450 BCE) through Ferrari's 1630 dedication to Cardinal Francesco Barberini, describes the manuscript's physical character (13 text folios, decorated initials, a closing Horace quotation visible on the final folio), and ends with direct links for readers to browse all 54 canvases on DigiVatLib.

The last scholarch's notebook: Olympiodorus on Plato, 1538

Vatican manuscript Vat.gr.275 — newly open on DigiVatLib in Week 24 of 2026 — contains the only two surviving Neoplatonic commentaries on Plato's Phaedo and Philebus by Olympiodorus the Younger (c. 495–570 CE), the last head of the Alexandrian philosophical school before Justinian's 529 CE closures. The 94-folio Greek manuscript was copied in 1538 by Giovanni Onorio da Maglie, the Vatican Library's official Greek scribe for nearly three decades, with a dated scribal subscription that pins its production precisely. Provenance traces to the Farnese family's Greek manuscript collection. All 202 canvases are freely accessible at DigiVatLib.

A 350-folio Gospel Harmony emerges from the Vatican vault

Vatican manuscript Ott.lat.2353 — the sole item digitized in DigiVatLib Week 24 (June 15, 2026) — turns out to be a substantial medieval Gospel Harmony (Concordia Evangelistarum): 350 folios of Latin text weaving all four Gospels into a single narrative, with a running apparatus of patristic marginal commentary visible on every page. The catalog provides no title, author, or date; three attached bibliographic references point to 12th-century Roman biblical scholarship (Nicola Maniacutia), 18th-century Vatican calligrapher Antonio Piaggio, and the 1748 Ottoboni collection acquisition. All 722 canvases are now freely accessible on DigiVatLib.
