ahh, the generally accepted English spelling for that Crimean kingdom seems to be Bosporan. Clearly derived from the same Greek word however, meaning strait. I used to live in Istanbul, so...a little confused when I saw Bosphoran troops coming from Scythia. I knew about the later use of Bosporan(Crimean one) troops by the Kiev-Rus, but was not aware that the same people were around in ancient times. Good stuff.
