This is an incredibly useful small book on number symbolism in Western occultism and alchemy. In this well-written and well-researched booklet, the author treats each number in turn, unpacking symbolism and iconography. The meanings are drawn from the Western hermetic tradition, i.e. neo-Platonism, medieval cosmology, astrology, music, gematria, Islam, kabbalah and magic squares. Paul Cowlan is a longstanding hermetic practitioner who brings a deep knowledge of Western esotericism to his booklets, which are well informed, clearly written and trustworthy reference works.
