I was also curious about this quote, and it sounded to me too like Donne (or Pascal or Robert Boyle, a bit).

But Gemini 3.0 knew what it was, and it is from Omar Khayyám like the sibling commenter said, but from the little-known E. H. Whinfield translation (1883) rather than the more famous Fitzgerald one:

—-

221. (395.)

Such as I am, Thy power created me,

Thy care hath kept me for a century!

Through all these years I make experiment,

If my sins or Thy mercy greater be.
