Samuil Marshak. (№ 413693)

Lazy time, as the sand flowed,
But he was captivated by our ancestors,
Found in it a harmony, and a measure, and a number,
Since then, it has lived in a clock, as in a cage.
The clock measures work and sleep,
Define meetings and separations.
For us hours calm, measured ringing -
Then peaceful, then combat sounds.
