Gao, Karveh or Karvah, a Persian blacksmith, whose sons had been slain to feed the serpents of the reigning tyrant, raised his leather apron on a spear, and with that for a standard excited a revolt; the revolt proved successful, and the apron became the standard of the new dynasty, which it continued to be till supplanted by the crescent.
