IULO. Iulus is another name for Ascanius, son of Aeneas and Creusa (Aeneid I.267, 288). Virgil says that Iulus was Ascanius's cognomen, or family name, from whom the family of Julius Caesar was supposed to have descended.

Chaucer says that Iulo is another son of Eneas, HF I.177. [Ascanius]

Iulo, Latin ablative singular of Iulus, occurs in final rhyming position.
