From the 16th century to the 18th century (when the sextant was invented) the astrolabe was the chief navigational instrument.
An astrolabe consists of a circle marked in degrees (similar to a protractor) with a rotating arm attached at its center. When the 0° mark on the circle is aligned with the horizon, and a star (or other celestial body) “sighted” at the end of the movable arm, the position (in degrees) of the star can be read (“taken”) off the calibrated circle (hence, “astro” = star + “labe” = to take).
