It will indicate the solar local time.

Planipherical Astrolabe Ref: LH-H22

HEMISFERIUM

The origins of the astrolabe were in classical Greece. It entered Europe from Moslem Spain with Latin words engraved alongside the original Arabic. Its peak of popularity was in the 15th and 16th centuries, when it was one of the basic astronomical education tools.
Astrolabes can be used to solve many astronomical problems that would otherwise require rather sophisticated mathematics. All of the everyday uses of the astrolabe are not known, but they were certainly used to tell time during the day or night, to find the time of sunrise and sunset, to locate celestial objects in the sky and also to determine aspects of horoscopes.
