North of there was a Roman city, Ourchinion. The western coastline was so distorted, however, that it is impossible to say where Adjacium was; certainly, he would have known its name and location if he had had any first-hand knowledge of the island and if in fact it was there. Ptolemy's Ourchinion is further north than Ajaccio and does not have the same name. It could be Sagone. The lack of correspondence between Ptolemaic and historical names known to be ancient has no defense except in the case of the two Roman colonies, Aleria and Mariana. In any case the population of the region must belong to Ptolemy's Tarabeni or Titiani people, neither of which are ever heard about again.
