Without having any contemporaneous account of the Bar Kokhba Revolt comparable to the writings of Josephus that describe the First Jewish Revolt, our knowledge about many aspects of the later uprising is rather sketchy. The publication of Roman military diplomas and the remarkable series of documents recovered from caves in the Judaean Desert, along with other major archaeological findings, has filled in just some of missing details. This study is devoted to a reexamination of the rebel coinage. It has highlighted the importance of the numismatic evidence in helping to elucidate the religious ideology that succoured the rebellion and shaped its leadership.
