开普勒墓志铭：我曾测量天空, 现在测量幽冥。灵魂飞向天国, 肉体安息土中。
Mensus eram coelos, nunc terrae metior umbras
Mens coelestis erat, corporis umbra iacet.
- Epitaph he composed for himself a few months before he died, as quoted in Calculusː Multivariable (2006) by Steven G. Krantz and Brian E. Blank. p. 126
- Unsourced variant: I used to measure the Heavens, now I measure the shadows of Earth. The mind belonged to Heaven, the body’s shadow lies here.
