The '''astrolabe''' was a compact round disc used to observe and calculate the position of celestial bodies before the invention of the [[sextant]]. It was the most widely used astronomical instrument of the Islamic and Medieval periods.
 
  
Astrolabes usually consisted of a flat disc with a sighting rod that could be pivoted to point at the [[Sun]] or bright stars. From the altitude of the Sun or star above the horizon, the local time could be estimated. <ref>A presentation for the Man & Technology Course (ES103) @ SUNY Farmingdale,by Gary Agranat & Dave Delligati, Fall 1980.
