Plato's description of Atlantis, as an island of concentric circles, in the two Socratic dialogues - Timaeus and Critias - 360 BCE, might be why Utopias are depicted as circular islands.
1) The Riccat Structure, "Eye of the Sahara"
Some say this was Atlantis. I don't think I agree but it does match a lot of the details of Plato's description, including it's size. I'm pretty sure of this though: it's weird.
