From the information of the peasants, Julian ascertained the vestiges of this ancient work, which were almost obliterated by design or accident. By the indefatigable labor of the soldiers, a broad and deep channel was speedily prepared for the reception of the Euphrates.

As it became necessary to transport the Roman army over the Tigris, another labor presented itself, of less toil, but of more danger, than the preceding expedition. The stream was broad and rapid; the ascent steep and difficult; and the intrenchments which had been formed on the ridge of the opposite bank, were lined with a numerous army of heavy cuirassiers, dexterous archers, and huge elephants; who (according to the extravagant hyperbole of Libanius) could trample with the same ease a field of corn, or a legion of Romans.
