Any recommendations for books on Ancient Greek colonies, particularly the ones established furthest from Greece? (along the coast of modern France and Spain, in the black sea, North Africa, etc.)

Of particular interest would be anything that goes into detail about the social history of these cities, how the Greeks who settled interacted with indigenous populations and how day to day life was led

PytheasTheMassaliot

For Massalia, Emporion and all the western Greek cities I can recommend Ancient Greek France by A. Trevor Hodge, The Extraordinary Voyage of Pytheas the Greek by Barry Cunliffe for an interesting point of view of the region and history, and Archaeologies of Colonialism. Consumption, Entanglement, and Violence in Ancient Mediterranean France by Michael Dietler for a more in depth view.

To begin with, you should definitely go for Ancient Greek France. It's the best easily readable, yet detailed source on this time period and region I have come across.
