Robert Place's book The Tarot takes up the Neoplatonic theory for the trumps. It's definitely worth reading.
le pendu said:Many people, including myself, would consider Wicked Pack of Cards to be essential reading for anyone seriously interested in tarot history. It's out of print, expensive, and hard to find. I personally find it to be the classic.
