Galon (Also called Guallo, Gualla, or Gualo), Giacomo
an Italian prelate, was born at Vercelli prior to 1150. He was canon-regular at Paris, and occupied from 1173 to 1185 the episcopal see of his native city. He distinguished himself by his zeal and virtue, and pope Innocent III accorded to him, in recognition of this, the cardinalate. Galon had charge of a mission in Languedoc, where he displayed great intolerance towards the Albigenses. He afterwards went to England on a diplomatic mission. Later, pope Honorius III sent him to the emperor Frederick II, to secure aid for the Christians in Palestine against the Mussulmans. Galon died at Vercelli in 1227. See Hoefer, Nouv. Biog.
