The Chaucer Review: An Indexed Bibliography (Vols. 1-30)

Donaldson, E. Talbot. "Venus and the Mother of Romulus: The Parliament of Fowls and the Pervigilium Veneris." 14 (1980): 313-18.
Chaucer took the reference to Rhea Silvia in the Parliament of Fowls from Pervigilium, not from Ovid, as has been previously suggested.
