The Nag Hammadi library is a collection of Gnostic texts discovered near the Upper Egyptian town of Nag Hammadi in 1945. Twelve leather-bound papyrus codices buried in a sealed jar were found by a local farmer named Muhammed al-Samman. The writings in these codices comprised fifty-two mostly Gnostic treatises, but they also include three works belonging to the Corpus Hermeticum and a partial translation/alteration of Plato's Republic. In his introduction to The Nag Hammadi Library in English, James Robinson suggests that these codices may have belonged to a nearby Pachomian monastery, and were buried after Saint Athanasius condemned the use of non-canonical books in his Festal Letter of 367 A.D. The discovery of these texts significantly influenced modern scholarship into early Christianity and Gnosticism.
