Lyrics (vowels in brackets are those that undergo elision; translation follows):
Auctor meus, miserere mihi,
Auctor mundi, avert(e) iram tuam.
Orig(o) omnis, miserere mihi,
Orig(o) animarum, avert(e) iram tuam.
Andraste, spons(a) Auctoris, audi me,
Andraste, sancta prophetis, audi me.
Redemptrix omnium, exaudi me,
Domina maeroris, exaudi me.
Ne patiamini animas piorum corrumpi,
in hor(a) aterrim(a) adiuvate servum vestrum humilem.
In nomin(e) Andrastes, fiat ita.
In nomin(e) Auctoris, fiat ita.
My Maker, have mercy on me,
Maker of the World, avert Thy wrath.
Origin of Everything, have mercy on me,
Wellspring of Souls, avert Thy wrath.
Andraste, Bride of the Maker, hear me,
Andraste, Holy Prophetess, hear me,
Redeemer of All, hear my prayer,
Lady of Sorrows, hear my prayer.
Let you not suffer the souls of the faithful to be corrupted,
in this darkest hour, aid your lowly servant.
In the name of Andraste, so let it be.
In the name of the Maker, so let it be.
Note: In the English version, "you" is used in the older sense of "you two" or "you all", while "thou" (or rather the possessive "thy") is used for the singular. Therefore, when asking for the Maker to avert His wrath, the penitent is addressing the Maker only. Later on, though, when asking for protection against corruption, they are addressing both the Maker and Andraste.
This distinction is also present in the Latin text.
