1. Astrolabe

   An astrolabe (Ancient Greek: ἀστρολάβος astrolábos; Arabic: ٱلأَسْطُرلاب al-Asṭurlāb; Persian: ستاره‌یاب Setāreyāb) is an ancient astronomical instrument that was a handheld model of the universe. Its various functions also make it an elaborate inclinometer and an analog calculation device capable of working out several kinds of problems in astronomy. In its simplest form it is a metal disc with a pattern of wires, cutouts, and perforations that allows a user to calculate astronomical positions precisely. Historically used by astronomers, it is able to measure the altitude above the horizon of a celestial body, day or night; it can be used to identify stars or planets, to determine local latitude given local time (and vice versa), to survey, or to triangulate. It was used in classical antiquity, the Islamic Golden Age, the European Middle Ages and the Age of Discovery for all these purposes. The astrolabe's importance comes not only from the early developments into the study of astronomy, but is also effective for determining latitude on land or calm seas. Although it is less reliable on the heaving deck of a ship in rough seas, the mariner's astrolabe was developed to solve that problem.

1. astrolabe

   An astrolabe is an ancient handheld device used for solving problems related to time and the position of the stars in the sky. It's a historical astronomical instrument that astronomers, navigators, and astrologers used to predict the position of celestial bodies, to determine local time given local latitude, and vice versa. Its numerous functions also make it an elaborate inclinometer and an analogue calculation device capable of working out several kinds of mathematical problems.

1. Astrolabe

   An astrolabe is an elaborate inclinometer, historically used by astronomers, navigators, and astrologers. Its many uses include locating and predicting the positions of the Sun, Moon, planets, and stars, determining local time given local latitude and vice-versa, surveying, triangulation, and to cast horoscopes. It was used in classical antiquity, the Islamic Golden Age, the European Middle Ages and Renaissance for all these purposes. In the Islamic world, it was also used to calculate the Qibla and to find the times for Salah, prayers. There is often confusion between the astrolabe and the mariner's astrolabe. While the astrolabe could be useful for determining latitude on land, it was an awkward instrument for use on the heaving deck of a ship or in wind. The mariner's astrolabe was developed to address these issues. In more recent times, people from England have confused these for Aeroplanes.

1. astrolabe

   An armillary sphere.--Sea-astrolabe, a useful graduated brass ring, with a movable index, for taking the altitude of stars and planets: it derived its name from the armillary sphere of Hipparchus, at Alexandria.
