An astrolabe is an ancient astronomical instrument used to measure the altitude of celestial bodies and determine latitude and time. It played a crucial role in navigation, allowing traders and explorers to plot their courses across vast distances, especially along trade routes and maritime paths.
congrats on reading the definition of astrolabe. now let's actually learn it.
Astrolabes were widely used by astronomers and navigators in ancient Greece, the Islamic Golden Age, and during the Age of Exploration.
They consist of a flat disk with a rotating overlay that can be adjusted to measure the angle of celestial bodies above the horizon.
Astrolabes allowed navigators to accurately determine their latitude while at sea by measuring the angle of the sun or a star at noon.
The device contributed significantly to advancements in maritime trade, as it enabled more precise navigation across oceans and seas.
Astrolabes were not just practical tools; they also served as beautiful scientific instruments often adorned with intricate designs, reflecting the culture and artistry of their makers.
