Smyrna was at the mouth of the small river Hermus and at the head of a deep arm of the sea (Smyrnaeus Sinus) that reached far inland. This enabled Greek trading ships to sail into the heart of Lydia, making the city part of an essential trade route between Anatolia and the Aegean. During the 7th century BC, Smyrna rose to power and splendor. One of the great trade routes that cross Anatolia descends the Hermus valley past Sardis, and then, diverging from the valley, passes south of Mount Sipylus and crosses a low pass into the little valley where Smyrna lies between the mountains and the sea. Miletus and later Ephesus were at the sea end of the other great trade route across Anatolia; for a time they successfully competed with Smyrna, but after both cities' harbors silted up, Smyrna was without a rival.
