A humanist's copy of Pliny the Younger's letters opens at the Vatican

At the top of the first leaf, square capital letters announce EPISTOLAE PLINII SECVNDI. Below the heading, an illuminated initial P in blue, red, and gold intertwines with white vine-stem ornament. The opening line begins with Pliny the Younger's greeting to his friend Septicius Clarus, urging the publication of his personal letters. The page belongs to Ott.lat.3305, a fifteenth-century paper codex held by the Biblioteca Apostolica Vaticana in Rome.

The Vatican Library added the manuscript to DigiVatLib during Week 36 of 2026. The independent tracker for Vatican additions records the item-level release on 9 September 2026, placing the digitization in the past week. 12

The Vatican catalog describes the codex as a fifteenth-century copy of Pliny's letters and identifies the hand as that of Sozomeno da Pistoia. 3 Born Zomino da Pistoia in 1387, the Tuscan scholar worked as a schoolmaster, canon of Pistoia Cathedral, and master of rhetoric and poetry at the Studio in Florence. 4

Sozomeno was among the early generation of Italian humanists who adopted humanist minuscule, the clear script modelled on early medieval Carolingian manuscripts. The script offered wide margins, upright letters, and generous spacing between words. Sozomeno copied dozens of classical Latin and humanist texts for his private library, which numbered over a hundred volumes. Before his death in 1458, he bequeathed his collection to the city of Pistoia for public use, creating an early Italian public library foundation. 4

Folio 1v reveals how Sozomeno structured the text on the page. The dedication to Septicius Clarus ends near the upper third of the leaf with the customary closing word Vale. A rubricated red heading follows, announcing the recipient of the next letter: Caninio Rufo salutem. A blue initial Q begins Pliny's affectionate inquiry into how his friend is spending his days on Lake Como: Quid agit Comum tuae meaeque deliciae?

Pliny the Younger, born Gaius Plinius Caecilius Secundus around 61 CE, pursued an active public career in imperial Rome. Adopted by his naturalist uncle Pliny the Elder, he served as magistrate, treasury administrator, consul, and provincial governor in Bithynia. 6

Pliny collected and polished his private correspondence into nine published books, composing letters on literary friendships, villa architecture, municipal finances, and political courtroom trials. 6 In two famous letters to the historian Tacitus, Pliny provided the sole surviving eyewitness account of the 79 CE eruption of Mount Vesuvius and the death of his uncle across the Bay of Naples. 7

Ott.lat.3305 preserves the texts that Italian Renaissance scholars sought out to reconstruct classical Latin style and Roman civic life. In Sozomeno's volume, the ancient text and the Quattrocento revival meet on the same leaf.

The complete 66-leaf digitized codex is free to inspect on DigiVatLib. The DigiVatLib viewer provides high-resolution zooms across all folios, including binding and endleaves.
