YSOPET

also spelled Isopet, in French literature, a medieval collection of fables, often versions of Aesop's Fables. The word was first applied to a collection of tales written by Marie de France in the late 12th century; they were said to be based directly on an English version of Aesop's Fables (Esope) attributed to King Alfred the Great, of Wessex, and no longer extant. Another source, better-documented, is the medieval Romuli (falsely credited to Romulus, son of Tiberius), which includes works of the Latin writers Phaedrus and Avienus.
