ARGYVE1 is the name of Criseyde's mother, Tr IV.762.
Neither Boccaccio nor Benoît mentions a mother for Criseyde.
Chaucer may have taken the name from Statius's Thebaid V.1509. Susan Schibanoff suggests that medieval etymology linked Argia/Argyve with a synonym for providentia. It is thus a redendnama, or "speaking name," which reveals the character of the person named. [Calcas: Creseyde]
