    That both astrology and alchemy may be regarded as fundamental aspects of thought is indicated by their apparent universality. It is notable, however, that the evidence is not equally substantial in all times and places. Evidence from ancient Middle America (Aztecs, Mayans) is still almost nonexistent; evidence from India is tenuous and from ancient China, Greece, and Islamic lands is only relatively more plentiful. A single manuscript of some 80,000 words is the principal source for the history of Greek alchemy. Chinese alchemy is largely recorded in about 100 “books” that are part of the Taoist canon. Neither Indian nor Islamic alchemy has ever been collected, and scholars are thus dependent for their knowledge of the subject on occasional allusions in works of natural philosophy and medicine, plus a few specifically alchemical works.
