Others conjecture that Dido was indeed historical, as described in the following accounts. It is unknown who first combined the story of Dido with the tradition that connected Aeneas either with Rome or with earlier settlements from which Rome traced its origin. A fragment of an epic poem by Gnaeus Naevius who died at Utica in 201 BC includes a passage which might or might not be part of a conversation between Aeneas and Dido. Servius in his commentary (4.682; 5.4) cites Varro (1st century BC ) for a version in which Dido's sister Anna killed herself for love of Aeneas.
