DAVID W. PANKENIER LEHIGHUNIVERSITY Thisarticle offers an accountof the ancientChinese system of judicialastrology known as "field- allocation"(fenye) astrology. This formof prognostication,premised on archaiccosmological con- ceptionsabout the correspondencebetween the celestialand terrestrial realms, is best knownin the highly systematizedand regularform preserved in sourcesof the WarringStates and Han periods. Thismature form was achievedafter a long processof evolutionand systematization. This studywill providea brief accountof this process and then illustratehow the principlesand astronomical observationsinvolved came to be appliedin two epochalmilitary and political contexts-the battle of Muye (1046 B.c.) and the battle of Chengpu(632 B.C.).Field-allocation astrology may have playeda significantrole in decision-makingin the earlyZhou.
