Why is it Used?
Ancient Astronomers noticed the stars never changed position relative to each other, they assumed they could map the stars because of this.

A heldheld device with a peephole.
You look through the hole to look at the stars and the string will dangle down.
The angle shown where the string falls is the height/altitude of the object being looked at.
