Persian names in Greece

Since Greeks were always pronouncing foreign names the way they liked and deemed easier for them and not the way they sounded in the native language, most of the names of ancient Persians, Egyptians, Skythians etc that we know are the way the Greeks pronounced them.

Coming back to your question, practically we pronounce ancient Persian names the way you see them in English (since they became known to the west from the Greek writers), with some minor differenciations.

E.g. Artaxerxes, Kyros (a friend of mine is married to a Persian lady and they named their son as Kyros - also an international Greek referee is named Kyros Vassaras), Dareios, Camvyses etc...

i think the only persian name used in greece today is Kyros

the italians use Dario and Cyrus

the greek "s" is an adaption of the persian "sh" seems the further west one goes people get lazier with words.

also is "v" in greek pronounced like english "b"?

In modern Greek, English B is pronounced as "mp", Greek letter "B" is equivalent in english as "V".

Some scholars maintain that in ancient Greek, B sounded like in today's modern English. Others disagree and it's quite difficult to ever know who's right and who's wrong.

Interesting, interesting.

In Spanish the V sounds like B, I thought it was the same in Greek, but it turns out to be the opposite.
