Astrolabes predated the compass and sextant, helping travelers navigate their journeys by point to the North Star. To use an astrolabe you would first need to be able to find the Big Dipper constellation, pointing your astrolabe towards these stars ensured that the handle on the face of the astrolabe would point to the North Star, therefore the traveler would always know which way was north. The many other uses of the astrolabe include, locating and predicting the positions of the sun, moon, planets, and stars, determining the local time given the local longitude and vice versa, surveying, and triangulation.
