1911 Encyclopædia Britannica/Patarenes

PATARENES, or Paratelli, a name apparently first used in Milan about 1058 to denote the extreme opponents of clerical marriages. The party was so called because, under the leadership of Arialdus, a deacon of Milan, its members used to assemble in the Pataria or ragmen’s quarter of that city (pates being a provincial word for a rag). In the 13th century the name was appropriated by the Cathari, who said it came from pati (to suffer), because they endured hardship for their faith. See Bogomils.
