I read once - somewhere - that the Marketplace of Carthage was called
"byrsa" - but that of course may have been a Greek transliteration or
perhaps simply a translation. Is it possible that the word was taken into
Greek from there? Cognates "market", "merchant" and the god Mercury, I have
long supposed. Would one of the Slavic-language speakers be kind enough to
tell me: do Slavic cognates carry the m- or the b/p- beginning? Thank you.
