Troy was placed where the poem said
Troy is a topic that has produced a lot of literature, but for thousands of years its location was forgotten. However the poet told us very clearly where it was buried; we only had to trust on his words.
The Iliad, Homer's poem, sings the war and destruction of Ilion, Troy. This city really existed on the coast of Asia Minor, now Turkey.
In fact there were several Troyas, the poem’s one is nothing less than the VI. The ancients did not bother too much to remove the rubble of a city devastated by war or by any natural or unnatural disaster. It was more convenient and less expensive to build on the ruins.
The site of Troy was discovered by the German Schliemann in 1870, because he had the ingenuity or the brilliant idea to blindly believe in the data brought by the poem itself, which Schliemann regarded as a historical narrative.
Perhaps this was that way because Schliemann was nothing but a German businessman who forged an enormous fortune, keen on archaeology, who could only go to college at age 44, getting a doctorate degree three years later.
This peculiar man, who also made other notable discoveries in Greece at Mycenae, Tiryns, Orchomenus, not only learned Greek, which rhythm and musicality made him fall in love without understanding a word, but also could speak 15 languages at age 33.
