Abstract
Analyzing the demise of religions is rendered considerably more difficult when lack of sufficient evidence causes gaps in historical understanding of the progressions of religions from being clearly alive to apparently no longer existing an acute problem with regard to most Greek and Roman religions. Drawing on the Ghost Dance religion as a parallel case and presenting by way of example considerations regarding emperor Julian's attempt to rebuild the Jerusalem temple, this article explores the common challenges of dearth of evidence, the need to argue from silence, and a 'religion' as category prone to (at least) the complication of transmutation.
