Ancient Troy was once a mythical city, known only through
the text of Homers Iliad. In 1870, however,
the German archeologist Heinrich Schlieman discovered the
ruins of Troy (and several cities above and beneath it) in
northwest Turkey. He located the city by scrutinizing the
text of the Iliad, and laboriously exploring the area on foot.
Modern scientists and archeologists use high technology
such as satellite imagery to aid their search for ancient historical sites. This image of the ruins of Troy from the IKONOS satellite uses four meter resolution color data.
