Roncalli was summoned to the final ballot of the conclave at 4:00 pm. He was elected pope at 4:30 pm with a total of 38 votes. After the long pontificate of Pope Pius XII, the cardinals chose a man who it was presumed because of his advanced age would be a short-term or "stop-gap" pope. They wished to choose a candidate who would do little during the new pontificate. Upon his election, Cardinal Eugene Tisserant asked him the ritual questions of whether he would accept and if so, what name he would take for himself. Roncalli gave the first of his many surprises when he chose "John" as his regnal name. Roncalli's exact words were "I will be called John". This was the first time in over 500 years that this name had been chosen; previous popes had avoided its use since the time of the Antipope John XXIII during the Western Schism several centuries before.
