Canon of the Mass (Latin: Canon Missæ, Canon Actionis) is the name given in the Roman Missal, from the first typical edition of Pope Pius V in 1570 to that of Pope John XXIII in 1962, to the part of the Mass of the Roman Rite that begins after the Sanctus with the words Te igitur. All editions preceding that of 1962 place the indication "Canon Missae" at the head of each page from that point until the end of the Mass; that of 1962 does so only until the page preceding the Pater Noster and places the heading "Ordo Missae" on the following pages.
