SIBILLE, SIBYLE. Sibyl was the name the Greeks and Romans gave to Apollo's prophetesses. The Cumaean Sibyl, who led Aeneas into the Cave of Avernus and later into the Underworld, was Apollo's priestess and prophetess (Aeneid VI.42-155).

The story of Eneas's descent, led by Sibyle, is painted on the brass tablet in Venus's temple, HF I.439-442. Cassandra, Apollo's priestess and seer, is called Sibille, Tr V.1450, when she comes to interpret Troilus's dream. [Cassandra]

Sibille, the ME variant, occurs medially, Tr V.1450; Sibyle occurs in final rhyming position, HF I.439.
