The term 'DIDO' and Aeneas refers to two characters in Virgil's epic poem, The Aeneid. DIDO was the founder and first queen of Carthage, while Aeneas was a Trojan hero who escaped the destruction of Troy and eventually founded Rome. DIDO and Aeneas had a passionate love affair, but ultimately Aeneas had to leave DIDO in order to fulfill his destiny. This story is a classic example of the conflict between fate and free will.
