What is the year Odysseus left Troy?

Odysseus left Troy after the city fell. Since that happened several thousand years ago and the event was not recorded in written form until several hundred years later, an exact date is not possible.

Troy VIIa has become the most likely candidate for the city whose destruction is described in Homer's Iliad. It was destroyed by fire around 1180 BC.

Troy VI, which was believed by many during much of the 20th century to be Homer's Troy, was destroyed, probably by earthquake, in 1275 BC
