How did astrolabes work?
An astrolabe is a device that uses astral bodies like the sun and stars to either tell your position in latitude or tell the local time. It can also be used to measure celestial events like the wobble of the Earth’s axis.
Why was astrolabe created?
Astrolabes were primarily invented by the ancient Greeks in 225 BCE by Apollonius based on the theories and the findings of Hipparchus. The main uses of astrolabes were to tell time during day or night, to identify the time of sunrise and sunset, and the length of the day, and to locate celestial objects in the sky.
