The Histories · 1.104

Now from the Maiotian lake to the river Phasis and to the land of the Colchians is a journey of thirty days for one without encumbrance; and from Colchis it is not far to pass over to Media, for there is only one nation between them, the Saspeirians, and passing by this nation you are in Media. However the Scythians did not make their invasion by this way, but turned aside from it to go by the upper road which is much longer, keeping Mount Caucasus on their right hand. Then the Medes fought with the Scythians, and having been worsted in the battle they lost their power, and the Scythians obtained rule over all Asia.
