Missa pro Defunctis: Sanctus and Agnus Dei

From Giovanni Vianini:



The Sanctus and the Agnus Dei in the Requiem Mass use the same texts as in all ordinaries of the mass - except that in the Agnus Dei, the petition miserere nobis (Have mercy upon us) is changed to dona eis requiem (Grant them rest), and dona nobis pacem (Grant us peace) to dona eis requiem sempiternam (Grant them everlasting rest):

Sanctus, Sanctus, Sanctus,
Dominus Deus Sabaoth;
pleni sunt coeli et terra gloria tua.
Hosanna in excelsis.
Benedictus qui venit in nomine Domini.
Hosanna in excelsis. (reprise)

Holy, Holy, Holy,
Lord God of Hosts;
Heaven and earth are full of your glory.
Hosanna in the highest.
Blessed is he who comes in the name of the Lord.



Agnus Dei, qui tollis peccata mundi, dona eis requiem,
Agnus Dei, qui tollis peccata mundi, dona eis requiem,
Agnus Dei, qui tollis peccata mundi, dona eis requiem sempiternam.

Lamb of God, who takes away the sins of the world, grant them rest,
Lamb of God, who takes away the sins of the world, grant them rest,
Lamb of God, who takes away the sins of the world, grant them rest, eternal.
