Near it is Patræus,921 a village, from which to Corocondame,922 a village, are 130 stadia. This is the termination of the Cimmerian Bosporus, as it is called. The narrow passage at the mouth of the Mæotis derives its name from the straits opposite the Achilleium, and the Myrmecium; it extends as far as Corocondame and a small village opposite to it in the territory of the Panticapæans, called Acra,923 and separated by a channel of 70 stadia in width. The ice reaches even to this place, for the Mæotis is frozen during severe frost so as to become passable on foot. The whole of this narrow passage has good harbours.
