They were variously referred to as the Runcarii, Babuni, Tisserands, and Poplicani. They trained an elite cast known as "the Elect" and among their observances were nudism, practiced by those who followed Cyril the Barefoot, and the frequent partaking in orgies, practiced by the followers of Theodosius. In one polity they ruled unopposed for 264 years as the Patarenes. Their main name translated as "Dear to God" in their native language, as revealed in the writing of Euthymius Zigabenus, who oversaw their trials under Alexius I Comnenius. Innocent III called for their destruction and considered them the eastern heretic counterpart to the Albigensians.
