I got this book to help me better understand number symbolism – the philosophy and relationship of numbers to themselves and to the cosmos – to apply this knowledge to the use of Tarot.
… medieval number philosophy, which often appears as sheer nonsense or at best as the product of extraordinarily confused thinking, is explicable only by reference to its origins. … It is the purpose of this study to reveal how deeply rooted in medieval thought was the conciousness of numbers, not as mathematical tools, nor yet as the counters in a game, but as fundamental realities, alive with memories and eloquent with meaning. … An important result of these studies has been to reveal in the medieval mind a web like structure of abstract ideas and concrete realities so closely interwoven and interdependent that no serious gap was felt to exist between them.
