Other tools that were used by Columbus for navigational purposes were the compass, hourglass, astrolabe, and quadrant.

How did the Romans navigate at sea?

When weather conditions were not good or where land was no longer visible, Roman mariners estimated directions from the pole star or, with less accuracy, from the sun at noon. They also estimated directions relative to the wind and swell. A lot of the Romans’ navigational skills were inherited from the Phoenicians.

How did sailors measure latitude?

To find the ship’s latitude, sailors used a tool called a sextant. The sextant measured the angle created by the noon sun, the ship, and the visible horizon. When the measurement of this angle was determined, it could be converted to degrees latitude by using a chart provided in the Nautical Almanac.
