Arithmologia

Arithmologia, sive De Abditis Numerorum Mysteriis is a 1665 work by the Jesuit scholar Athanasius Kircher. It was published by Varese, the main printing house for the Jesuit order in Rome in the mid-17th century. It was dedicated to Franz III. Nádasdy, a convert to Catholicism to whom Kircher had previously co-dedicated Oedipus Aegyptiacus. Arithmologia is the only one of Kircher's works devoted entirely to different aspects of number symbolism.
