In the opening chapter of his thirty-sixth oration, Dio Chrysostom tells his listeners how in the course of a journey ‘through the lands of the Scythians to that of the Getae’, he stopped over in the city of Borysthenes (Olbia) ‘in the summer after my exile’ (τὸ θέρος … μετὰ τὴν φυγήν). Dio had been exiled by Domitian, probably in a.d. 83 or 84; since his exile ended after the death of Domitian in September 96, it is generally accepted that his visit to Borysthenes took place in the summer of 97.
