The Beauty of Latin

Dies iræ! dies illa
Solvet sæclum in favilla:
Teste David cum Sibylla!

Recordare, Iesu pie,
Quod sum causa tuæ viæ:
Ne me perdas illa die.
The day of wrath, that day
Will dissolve the world in ashes
As foretold by David and the sibyl!

Remember, merciful Jesus,
That I am the cause of thy way:
Lest thou lose me in that day.

—Mass for the Dead, sequence by Thomas of Celano (c. 1200-1260)
