On receiving this reply, the satrap immediately despatched a powerful Persian armament, land-force as well as sea-force, in fulfilment of the designs of Pheretime against Barka. They besieged the town for nine months, trying to storm, to batter, and to undermine the walls ; a but their efforts were vain, and it was taken at last only by an act of the grossest perfidy. Pretending to relinquish the attempt in despair, the Persian general concluded a treaty with the Barka;ans, wherein it was stipulated that the latter should con- tinue to pay tribute to the Great King, but that the army should retire without farther hostilities : " I swear it (said the Persian general), and my oath shall hold good, as long as this earth shall keep its place." But the spot on which the oaths were ex changed had been fraudulently prepared : a ditch had been excavated and covered with hurdles, upon which again a surface of earth had been laid. The Barkaeans, confiding in the oath, and overjoyed at their liberation, immediately opened their gates and relaxed their guard ; while the Persians, breaking down the hurdles and letting fall the superimposed earth, so that they might comply with the letter of their oath, assaulted the city and took it without difficulty. Miserable was the fate which Pheretime had in reserve for these entrapped prisoners. She crucified the chief opponents of herself and her late son around the walls, on which were also aifixed the breasts of their wives : then, with the exception of such of the inhabitants as were Battiads, and noway concerned in the death of Arkesilaus, she consigned the rest to slavery in Persia. They were carried away captive into the Persian empire, where Darius assigned to them a village in Baktria as their place of abode, which still bore the name of Barka, even in t he days of Herodotus. During the course of this expedition, it appears, the Persian army advanced as far as Hesperides, and reduced many of the Libyan tribes to subjection : these, together with Kyrene and 1 Polyaenu.
