i did pericles as our personality.. i don't think modern scholars approach pericles any different to ancient scholars; rather, its more the different opinions amongst scholars.
you've probably looked at these, but for ancient scholars u wanna look at plutarch [life of pericles] as ur main src of info... as well as thucydides [peloponnesian wars] and aristotle [the athenian constitution].
for modern scholars...*thinks* i used A.R. Burn, R Meiggs, and Diane Kagan... but of course, theres heaps others.
good luck!
