He was also called Iulus or Julus. From this name comes the Gens Julia, the Julian family to which Julius Caesar belonged.
The name Iulus was popularised by Virgil in his work the Aeneid, replacing the Greek name Ascanius by Iulus to try and link the Julian family of Rome to previous mythology. The emperor Augustus, who commissioned the work, was a member of the Julian family, so by spreading around, through his many poets (he was thought of as a great patron of the arts), his direct descent from Aeneas, he could claim to have three major Olympian gods in his family tree.

Aeneas' son Iulus is the subject of chapter 5; this is the best chapter in the book largely because P. traces not only the role of Iulus in the poem but the implications of that role for the ultimate success or failure of Aeneas' mission.
The neglected Iulus is a hard character to assess, and here P.'s model of heroic initiation works particularly well: we see Iulus as child, as temporarily fatherless, and as warrior.
Iulus holds out the promise that the darkness of Troy's final night, a darkness P. associates with treachery in the Trojan past, will not be carried with him into the future.
