FLEXIPPE is one of Criseyde's nieces. Boccaccio does not mention nieces in Il Filostrato (1333-1339); Chaucer has invented the garden scene in which they appear, Tr II.813-819. [Antigone: Creseyde: Tharbe]
Flexippe is perhaps derived from Phlexippi, genitive singular of Phlexippus (Met VIII.440) and appears initially, Tr II.816.
