Lyrics:

Mors stupebit et natura
Cum resurget creatura
Mors stupebit et natura
Gere curam mei finis

Lacrimosa dies illa
Resurget ex favilla
Judicandus homo reus
Huic ergo parce Deus

Mors stupebit et natura

Translation:

Death and nature will marvel,
when the creature arises,
Death and nature will marvel,
perform the healing of mine end.

Tearful will be that day,
on which from the ash arises
the guilty man who is to be judged.
Spare him therefore, God.
