Seneca · On care of health and peace of mind

Letters 104.24

It is superior to all, monarch of all it surveys; hence it should be subservient to nothing, finding no task too heavy, and nothing strong enough to weigh down the shoulders of a man.

Shapes dread to look upon, of toil or death

are not in the least dreadful, if one is able to look upon them with unflinching gaze, and is able to pierce the shadows. Many a sight that is held a terror in the night-time, is turned to ridicule by day. “Shapes dread to look upon, of toil or death”: our Vergil has excellently said that these shapes are dread, not in reality, but only “to look upon"—in other words, they seem terrible, but are not.
