I may stand in need of some apology for having used, without scruple, the authority of Constantine Porphyrogenitus, in all that relates to the wars and negotiations of the Chersonites. I am aware that he was a Greek of the tenth century, and that his accounts of ancient history are frequently confused and fabulous. But on this occasion his narrative is, for the most part, consistent and probable; nor is there much difficulty in conceiving that an emperor might have access to some secret archives which had escaped the diligence of meaner historians. For the situation and history of Chersone, see Peyssonel, des Peuples barbares qui ont habite les Bords du Danube, c. xvi. 84-90.
