protest sent by the Cardinals to Raynerius Gatti, Captain of the City of Viterbo, to cease and desist from their harassment of the Cardinals and their suites. He was one of the cardinals who signed the electoral compact on September, 1270, to leave the election of a new pope to a committee of six, promising to accept the committee's decision. He was not, however, one of the six cardinals elected to the Compromise Committee that selected Archdeacon Teobaldo Visconti as pope on 1 September 1270. The newly elected pope was not present in Viterbo, but was serving on Crusade with King Edward I of England. He arrived in Italy on 1 January 1271, and travelled to Viterbo, where he arrived early in February. He accepted the election, and chose to be called Gregory X. He and the Curia travelled to Rome, arriving on 13 March. On 19 March he was ordained a priest, and on 27 March he was consecrated bishop, and then crowned by Cardinal Giovanni Gaetano Orsini. Three Conclaves of 1276 Simon de Brion's appointment as Legate in France, made by Pope Gregory on 1 August 1274 continued throughout 1276. He was unable to be present for the Conclave of 1 January 1276, which elected Peter of Tarantaise as Pope Innocent V. Nor was he present for the Conclave of 2–11 July, which elected Ottobono Fieschi as Pope Adrian V. Nor was he present at the September Conclave, which, on 8 September, elected Peter Julian as Pope John XXI. In each case the election was completed before he could have been notified, and before he could have travelled from France to central Italy. This was one of the defects of Gregory X's regulations on the holding of a Conclave. Election of Nicholas III Pope John XXI was in contact with Cardinal Simon. He had written to him on 3 March 1277, ordering him to speak with the king of France about matters connected with Alfonso of Castile. But the Pope died rather suddenly, after a reign of only eight months. He was still living in the Episcopal Palace in Viterbo, where Adrian V (Fieschi) had died and where he had been elected. The palace was still under construction, when suddenly the roof of one of the chambers collapsed. The Pope was in the room at the time, and he was severely injured. He died three (or six) days
