So I have a question on the name of the city now most referred to as Troy. As I understand it, the Greek name for this place was Ilios (or something to the like), which is why Homer named one of his epics the Iliad. So why do we currently call it Troy and the Trojan war? Where and how did we switch from Ilios to Troy between Homer and now? Is this something modern or did this name change already happen in ancient times?
