Spem in alium (Latin for "Hope in any other") is a 40-part Renaissance motet by Thomas Tallis, composed in c. 1570 for eight choirs of five voices each, considered by some critics to be the greatest piece of English early music. Along with Tallis's Lamentations, H. B. Collins described it in 1929 as Tallis's "crowning achievement".

English translation:
I have never put my hope in any other
but in You, O God of Israel
who can show both anger and graciousness,
and who absolves all the sins
of suffering man
Lord God,
Creator of Heaven and Earth
be mindful of our lowliness
