A good man who sought to protect the earth from heavenly dangers now goes to heaven.
I used to measure the heavens,
now I shall measure the shadows of the earth.
Although my soul was from heaven,
the shadow of my body lies here.
... The latin jacet is a word play. It means "cast", but came to mean "lies" in the sense of "cast down". Poetically, I think the last line might be rendered,
My mind was in the heavens, my body's shadow is cast here.
