 When Paris is helping the citizens of Troy escape, he hands Priams  sword to a young man named Aeneas and tells him that as long as the  sword is in the hands of a son of Troy, the Trojans will survive.  This is an obvious reference to Virgils epic poem, The Aeneid,  which tells the story of a prince of Troy named Aeneas leading the  survivors of Troy through a series of hardships before finally  settling in Italy where his descendants where to found Rome 5  centuries later. However, Aeneas was the second greatest warrior the  Trojans fielded during the war according to The Iliad, and was the  son of Venus. These facts were also neglected in the movie and  instead Aeneas was relegated to the role of a young boy. That boy  should have been instead his son Julus, founder of the family of  Caius Julius Caesar.
