Astrolabe An astrolabe is an astronomical computer used to determine the time based on the position of the Sun and the stars. Thanks to this, centuries ago it was possible to know what time it was. This question, which seems trivial today, was once a great challenge in the pre-smartphone era. With its help, it was possible to determine the timing of phenomena such as sunrises and sunsets, and it allowed for the determination of star positions and directions. It was used to perform many advanced calculations. The astrolabe reproduced a 3D sky map on a flat surface. It was also a navigation tool. Its history began more than 2,000 years ago. Over the centuries, knowledge developed, and increasingly complex devices were built. Much credit for this goes to Arab scholars. According to sources, thanks to this device, a very accurate map of Baghdad, for example, was created in the Middle Ages. It is thanks to them that the astrolabe reached Europe in the 12th century. Until about 1650, it was the most common astronomical instrument, after which it was replaced by more accurate devices.
