Zanzis

Zanzis (or possibly ‘Zauzis’),
a wise writer referred to by Chaucer in Troilus and Criseyde (IV. 414), referring to Zeuxis who is a sage in the Alexander story. The form may come from a misreading of the text of Boccaccio that Chaucer is following; but this is unlikely, since the Athenian painter Zeuxis is called ‘Zanzis’ in ‘The Physician's Tale’ (see Canterbury Tales , 13; vi. 16).
