The landing-place on the east bank is at Tell Aḥmar, a tiny hamlet which has inherited the site of a very ancient city. Here perhaps Strabo’s road crossed the river;[19] here Julian may have constructed his pontoon bridge, and it is not improbable that for the first four or five hundred years of the Christian era it was the customary point of passage for travellers from Hierapolis to Edessa.[20] Thapsacus, which lies lower down than Cæciliana-Ḳal’at en Nejm, was of earlier importance. Xenophon crossed there, and nearly a hundred years later, Darius, fleeing headlong eastwards with his broken army after the battle of Issus, with Alexander headlong at his heels, passed over the river at Thapsacus.[21]
