If any confirmation were required of the evidence supplied by tbe first inscription published in the J.H.S. 1904, as to the ancient name of Dorla, it would be found in the Roman accounts of the siege of Isaura by Servilius Isauricus. Frontinus, iii. 7, 1, says that Servilius compelled the city to surrender from thirst, flumine ex quo hostes aquabantur averso. Now there are very few cases in which such an operation is possible. Three conditions must be fulfilled: (1) the city must be dependent for its water almost entirely on a river flowing through it or close to the wall; (2) there must be open ground on the opposite side of the river towards which the water can be diverted; (3) the operation must not be on so great a scale as to be beyond the power of an army such as Servilius had with him, a comparatively small and rather lightly equipped force, able to cross the Taurus from Cilicia, and operate on the northern flanks of the mountains.
