Zairja
From Wikipedia, the free encyclopedia
A zairja was a device used by medieval Arab astrologers to calculate ideas by mechanical means. It used the 28 letters of the Arabic alphabet to signify 28 categories of philosophic thought. By combining number values associated with the letters and categories, new paths of insight and thought were created.
It is thought that Spanish mystic, Ramon Llull (1234-1315) in his travels and studies of Arab culture, became familiar with the zairja, and used it as a prototype for his invention of the Ars Magna (The Great Art).
