The Greek astrolabe was a pivotal astronomical instrument that enabled ancient astronomers to measure the positions of stars and planets, facilitating advancements in navigation and timekeeping. Its design allowed for intricate calculations of celestial phenomena, influencing both science and philosophy. The principles of the astrolabe laid the groundwork for later developments in astronomy and navigation, making it a crucial tool in the evolution of these fields. Today, it is celebrated for its historical significance and its role in the development of scientific instruments.

Astrolabe
Greek astron "star" and lambanein "to take".
From Greek astron "star" and lambanein "to take". It permits astral navigation and mapmaking.
The astrolabe was developed by ancient Greek astronomers, likely during the 2nd century BC. They improved upon earlier devices to create a sophisticated instrument used for solving problems related to time and the positions of celestial objects.
Hipparchus, or more correctly Hipparchos (Greek: Ἵππαρχος,Hipparkhos; c. 190 BC - c. 120 BC)
The astrolabe was important for early exploration because it allowed sailors to determine their latitude by measuring the angle of celestial bodies, primarily the sun or stars, above the horizon. This helped them navigate more accurately and chart their course at sea.

Muslim scientists who studied the heavens perfected the Greek astrolabe. Sailors use this tool to study the stars and determine their location at sea. They used the astrolabe to measure the size and distance around the Earth. Based on the measurements they figured out Earth is round.
It is a mediaeval instrument for measuring the altitude of the sun and other sky objects, now replaced by the sextant.
