 It is described by Theophanes of Byzantium as situated in a plain between the two Taurus Mountains, a description which exactly, corresponds to the position of the basin of the Calycadnus.Claudiopolis may therefore be represented by Mut, which is higher up the valley than Seleucia, and near the junction of the northern and western branches of the Calycadnus.It is also the place to which the pass over the northern Taurus leads from Laranda.
