There was an aborted project under Roman emperor Julian (361–363 CE) to rebuild the Temple. Julian is traditionally called Julian the Apostate due to his policy of reversing Emperor Constantine's Christianization campaign by restoring traditional religious practices and holy places across the Empire. As part of this policy, Julian permitted the Jews to build a Third Temple. Rabbi Hilkiyah, one of the leading rabbis of the time, spurned Julian's money, arguing that gentiles should play no part in the rebuilding of the temple.
