Nero claimed to be a descendant of Aeneas -- a legendary hero of the Trojan War, as Homer tells it in the Iliad -- and was a big fan of Trojan heroics. He had the ceilings of his palace adorned with mythical scenes from the Trojan War, some of which are now on display at the Palatine Museum next door.
