The Penguin Historical Atlas of Ancient Greece
This well-illustrated volume is just the thing to have on hand while working your way through  the pages of Xenophon, Herodotus, and Thucydides. Robert Morkot traces the growth of Greece from a  series of often conflicting city-states, each with its own colonial outposts as far from home as Spain and  Tunisia, to loosely knit alliances that waged huge conflicts against the Persian empire--and, as in the case  of the Peloponnesian War, against each other. The pages devoted to Alexander the Great, which show how  the Greek empire came to extend from southern Egypt to the gates of China are particularly interesting.
