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.

Augustine's City of God in Italian: a 16th-century reading copy opens at the Vatican

The translation descends from the only known medieval Italian version, by Dominican friar Jacopo Passavanti (c. 1302–1357). The manuscript passed through Queen Christina of Sweden's Roman library before the Ottoboni family transferred it to the Vatican in 1748. Now freely readable on DigiVatLib as part of the Week 23 batch.

The book that fits in your palm: a Roman poet's love songs, copied by a student of Rome's most dangerous teacher

Vatican manuscript Ott.lat.2857, digitized June 10, 2026 as part of DigiVatLib's Week 23 batch, is a tiny parchment-and-paper codex (123 × 110 mm, roughly smartphone-sized) containing the complete Tibullus elegies, made around 1475–1500 by a student of the controversial humanist Pomponio Leto — whose semi-secret Roman Academy was once raided by papal order. The manuscript's most striking feature is folio 65v: the poet's epitaph rewritten in capital letters inside a drawn rectangular frame, designed to look like a Roman gravestone. Provenance runs from Fabio Farnese (Knight of Malta) to Fulvio Orsini to Philipp von Stosch before entering the Vatican in 1748.

The spy's book: Rome's oldest geography, bound with its gods

Vatican manuscript Ott.lat.2848, published on DigiVatLib in the Week 23 batch (June 2026), is a two-part paper codex from 15th–16th-century Rome: 30 folios of Pomponius Mela's De Chorographia — the only standalone geography to survive from classical Latin, composed c. AD 43–44 — followed by 10 folios of a 16th-century alphabetical miscellany on Roman religion, opening with the goddess Angerona. The manuscript's spine bears the ex-libris of Baron Philipp von Stosch, a Prussian gem collector, British spy, and Masonic lodge founder, before the Vatican purchased his library in 1759 and absorbed it into the Ottoboni fond.

The manuscript two scribes finished, 150 years apart

Vatican manuscript Vat.gr.1294, digitized on June 10, 2026, is a 14th-century Greek codex containing Aristophanes' four surviving comedies (with scholia), Aristotle's Ethica and Organon, and Stephen of Byzantium's geographical dictionary — all in a single binding. Its defining feature is a seam on folio 249r where the original 14th-century hand gives way to a section added roughly 150 years later by Zacharias Kallierges, the Cretan calligrapher who established Rome's first Greek printing press. The manuscript passed through the collection of Renaissance bibliophile Fulvio Orsini before entering the Vatican Library in 1602 as part of his 416-manuscript bequest. It is now freely viewable on DigiVatLib — the first Greek-language manuscript in this channel's Vatican coverage.

The poem Petrarch kept rewriting until his death

Vatican manuscript Ott.lat.2892, newly digitized June 9, 2026, is a 15th-century paper codex of Francesco Petrarch's complete I Trionfi (The Triumphs) — the allegorical epic in terza rima that was once Petrarch's most widely read work, inspiring Renaissance tapestries, wedding-chest paintings, and possibly the structure of early tarot. The manuscript, 57 folios with a single decorated initial, passed through Queen Christina of Sweden's legendary collection before entering the Vatican's Ottoboniani holdings in 1748. It is now freely viewable on DigiVatLib.
