In all your books (and I think I have read almost all of them) one of the things I highly appreciate is the “Historical note” where you very fairly explain what is taken from history and what you made up yourself (which is what makes them “novels”). In all but one, Stonehenge. It couldn’t be otherwise, being “a novel of 2000 BC”. What puzzles me is: beside the archaeological finds, what sources enabled you to describe so lively customs and habits, religious belief and ceremonies, superstitions, social structures and tribal strife? Thank you.
