Nicole Oresme Quote

The heavenly bodies move with such regularity, orderliness, and symmetry that it is truly a marvel; and they continue always to act in this manner ceaselessly, following the established system, without increasing or reducing speed and continuing without respite, as the Scripture says: Summer and winter, night and day they never rest.

Book II, Ch. 2, p. 283. - Le livre du ciel et du monde (1377)
