Madur, in Antiquity known as Theches (), is a mountain in Sürmene, Turkey.
Thálatta! Thálatta! ( â "The Sea! The Sea!") was the shouting of joy when the roaming 10,000 Greeks saw Euxeinos Pontos (the Black Sea) from Mount Theches (ÃÂîÃÂ÷ÃÂ) in Trebizond, after participating in Cyrus the Younger's failed march against the Persian Empire in the year 401 BC. The mountain was only a five-day march away from the friendly coastal city Trapezus. The story is told by Xenophon in his Anabasis.
