Jacobus de Voragine
The bonnacon is also mentioned in the life of Saint Martha in the "Golden Legend", a 13th-century hagiographical work by Jacobus de Voragine. In the story, Saint Martha encounters and tames the Tarasque, a dragon-like legendary creature said to be the offspring of the biblical Leviathan and the bonnacon. In this account, the bonnacon (here: bonacho or onacho) is said to originate in Galatia.
