He was papal secretary—notarius sacri palatii — at Avignon, went with Gregory XI. to Rome, was there at the breaking out of the schism, and held official positions under three of the popes of the Roman line. In 1408 he joined the Livorno cardinals, and supported Alexander V. and John XXIII.—See H. V. Sauerland: D. Leben d.
