My new book about Acheloios and Thales should be available soon. It is
part of a new series--Archaeology and Classical Humanities.
Not many people realize that philosophy (traditionally understood) and coinage emerged in nearly the same place at the same time, and that the two enterprises share an intimate bond--according to some commentators (not me), coinage literally caused philosophy. If you are interested in the intersection of philosophy and
numismatics you'll love this book, I guarantee it!
I'll post links when it is available!
