Background Innocent III first mooted organizing an ecumenical council in November 1199. In his letter titled Vineam Domini, dated 19 April 1213, the Pope writes of the urgent need to recover the Holy Land and reform the Church. The letter, which also served as a summons to an ecumenical council, was included alongside the Pope's papal bull Quia maior. In preparing for the council, the Pope spearheaded the extensive refurbishment of the old St. Peter's Basilica, which he designated as the "centrepiece for display and decoration" during the council. The lunette of the main door leading to the tomb of St. Peter had engravings of Old Testament prophets and twenty-four bishops, alongside the messages, "Feed your Sheep" and "This is the Door of the Sheep".
