Edition of 64 Aesopic, and 18 fables of Avianus in Latin and Old French. The Aesopic fables are, with a few exceptions, derived from the paraphrase of Romulus in distichs known as "Esopus moralisatus" ("Anonymus Neveleti") by some authorities ascribed to Walter of England. - The text is based in the main upon three closely related illustrated mss. of the 14th century (Brussels, Bibl. roy. 11193; Brit. mus. Add. 33781; Paris, Bibl. nat. fonds franç. 1594). The title "Ysopet-Avionnet" was originally given to the fables of Avianus alone (cf. A.C.M. Robert, Fables inédites ... vol. I,1825). In this edition it denotes the 2 parts - Isopet or Aesop, and Avionnet or Avianus.
