Next after the Poseidium of the Milesians, eighteen stadia inland, is the oracle of Apollo Didymeus among the Branchidae.1
It was set on fire by Xerxes, as were also the other temples, except that at Ephesus. The Branchidae gave over the treasures of the god to the Persian king, and accompanied him in his flight in order to escape punishment for the robbing and the betrayal of the temple. But later the Milesians erected the largest temple in the world, though on account of its size it remained without a roof. At any rate, the circuit of the sacred enclosure holds a village settlement; and there is a magnificent sacred grove both inside and outside the enclosure; and other sacred enclosures contain the oracle and the shrines. Here is laid the scene of the myth of Branchus and the love of Apollo. The temple is adorned with costliest offerings consisting of early works of art. Thence to the city is no long journey, by land or by sea.
