Apuleius's novel was among the ancient texts that made the crucial transition from roll to codex form when it was edited at the end of the 4th century. It was known to Latin writers such as Augustine of Hippo, Macrobius, Sidonius Apollinaris, Martianus Capella, and Fulgentius, but toward the end of the 6th century lapsed into obscurity and survived what was formerly known as the "Dark Ages" through perhaps a single manuscript. The "Metamorphoses" remained unknown in the 13th century, but copies began to circulate in the mid-1300s among the early humanists of Florence. Boccaccio's text and interpretation of "Cupid and Psyche" in his "Genealogia deorum gentilium" (written in the 1370s and published 1472) was a major impetus to the reception of the tale in the Italian Renaissance and to its dissemination throughout Europe.
