THARBE is one of Criseyde's nieces, with whom she walks in the garden while Antigone sings a song of love, Tr II.813-825. She accompanies Criseyde to dinner at Deiphebus's house, Tr II.1562-1563.
G.L. Hamilton suggests that Chaucer found the name "rex Thabor" in the Historia destructionis Troiae and made it feminine. [Antigone: Creseyde: Flexippe]
The name appears medially, Tr II.816, 1563.
