What's up, homies?

But heeeeey, is that settlement on the eastern coast of Spain, called Arse, the exact same settlement that Hannibal famously stormed (Saguntum)? Also, is it the same thing as this map's Zakynthos? I've read that Zakynthos is a Greek colony; so, if these 3 names are all the same thing for one city, here's my real question: is EB's settlement of Arse a Greek colony? Further, what would the Greeks have called it? Arse, Saguntum, or Zakynthos?
