My M.A. thesis was on this topic. I was initially enthusiastic about the exciting prospect that Pyrrho "reinvented" Buddhism in Ancient Greece (ref. Kuzminsky), but the empirical evidence simply isn't there yet. The scepticism propounded by Sanjaya Belathiputta (sp?) seems like a better match at present, though I'm looking forward to future scholarship on the topic

That's an awesome work. I referenced it repeatedly in my M.A. thesis, which was about the question of Buddhist influence on Pyrrho of Elis. I strongly agree that anyone interested in East-West comparative philosophy should absorb this book. Cheers
