The hour is named after the Egyptian god Horis.

Qué hora?

In Spanish literally means, Where is Horis.

We also get horizon from this term.

The ancient symbol for the sun is a circle with a dot in the middle. This is a watch face.

You have an hour hand (Horis) and a minute (moon) hand.

The diameter of a circle comes from the root of Dios, Theo, Zeros, Deva which all are roots to the term for God/God's which literally means light.
