The Vatican is releasing details of the pope's installation Mass on Tuesday as well images of his coat of arms and fisherman's ring.
In addition to more than 132 government delegations, the Vatican said 33 Christian delegations will be present, as well as representatives from Jewish, Muslim, Buddhist, Sikh and Jain communities.
The ring that Pope Francis will put on during the Mass once belonged to Pope Paul VI, and is made of gold-plated silver.
Francis' papal coat of arms is based on the same simple one as he had previously, with the symbol of his Jesuit order with the addition of the papal symbols of a bishops' miter and gold and silver-crossed keys.
A gold star representing the Virgin Mary, and the nardo, a grape-like plant with which St. Joseph is often represented, are painted on a bright blue background. Above them is the emblem of Francis' Jesuit order. Together the three represent Jesus, Mary and Joseph. (AP)
