Historians think that the Iliad was a dramatised telling of a real event and I was wondering if the same could be said about the Aeneid.
Not to discourage any further answers, but there's a few old threads that might be helpful to you (although some aren't as in-depth as more recent answers:
Is there some truth in the myth of Aeneas coming to Italy and founding Rome ? by /u/akyser
Before Virgil and the Aeneid, did Romans believe that Aeneas founded the Roman race? by /u/BaffledPlato
Who was Aeneas before the Aeneid? with /u/heliotach712 and /u/XenophonTheAthenian
Concerning your statement about the Iliad, you might want to check out this answer by /u/Iphikrates and this thread with a now deleted user about historians' perspectives of whether it is based on a real event.
