sundial

Ancient time teller

A sundial is a device that tells time by the position of a shadow cast by the sun.

A raised element (the gnomon) casts a shadow onto a marked surface, indicating the hour as the sun moves across the sky.

Sundials were the primary timekeeping instruments before mechanical clocks: The garden featured an old stone sundial.
