In summoto loco partis meridianae murorum, quae despectat fluvium Tigrim, turris fuit in sublimitatem exsurgens, sub qua hiabant rupes abscisae, ut despici sine vertigine horrenda non posset, unde cavatis fornicibus subterraneis, per radices montis scalae ad usque civitatis ducebant planitiem, quo ex amnis alveo haurirentur aquae furtim, ut in omnibus per eas regiones munimentis quae contingunt flumina vidimus, fabre politae.
In a remote part of the walls on the southern side, which looks down on the river Tigris, there was a tower rising to a lofty height, beneath which yawned rocks so precipitous that one could not look down without shuddering dizziness. From these rocks subterranean arches had been hollowed out, and skilfully made steps led through the roots of the mountain as far as the plateau on which the city stood, in order that water might be brought secretly from the channel of the river, a device which I have seen in all the fortifications in those regions which border on streams.
