The tale of Troy is told by Homer with the Iliad and the Odyssey. Homer was drawing on a vast cycle of stories about Trojan War. The Iliad includes a few weeks in the tenth year of the war.
According to Greek sources, Troy stood near the Dardanelles. There was no dispute about its location in the story were al familiar: the Dardanelles, the islands of Imbros, Samothrace and little Tenedos, Mount Ida to the south east, the plain and the river Scamander. It was an ancient city an its inhabitants were known as Teucrians or Dardanians but also as Trojans or Ilians which got this name from eponymous hereos, Tros and his uncle Ilus, the inventors of the city. In other source mentioned that Troy and Ilius were two seperate places but Homer insists on using these two names for Troy. there was no explanation about that.
