The Truth Of Troy

Troy (Greek: Τροία, Troia, also Ἴλιον, Ilion; Latin: Trōia, Īlium; Hittite: Wilusa or Truwisa) is a legendary city and center of the Trojan War, as described in the Epic Cycle and especially in the Iliad, one of the two epic poems attributed to Homer. Trojan refers to the inhabitants and culture of Troy.

Today it is the name of an archaeological site, the traditional location of Homeric Troy, Turkish Truva, in Hisarlık in Anatolia, close to the seacoast in what is now Çanakkale province in northwest Turkey, southwest of the Dardanelles under Mount Ida.
A new city of Ilium was founded on the site in the reign of the Roman Emperor Augustus. It flourished until the establishment of Constantinople and declined gradually during the Byzantine era.
In 1865 an English archeologist, Frank Calvert, excavated for many years the site at Hisarlık, near Truva, where in 1870 a wealthy German businessman, Heinrich Schliemann, also began excavating in this area which he claimed to be the ancient city of Troy. Later excavations revealed several cities built in succession to each other. One of the earlier cities (Troy VII) is generally identified with Homeric Troy. While such an identity is disputed, the site has been successfully identified with the city called Wilusa in Hittite texts; Ilion (which goes back to earlier Wilion with a digamma) is thought to be the Greek rendition of that name.
