Multiple choice

What was the primary motivation for the development of the astrolabe in medieval Europe?

  1. Navigation

  2. Timekeeping

  3. Astronomy

  4. Cartography
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The astrolabe was primarily developed as a navigational tool to determine the latitude of a ship at sea. It allowed sailors to measure the angle between the horizon and the sun or stars, which could then be used to calculate their latitude.
