An astrolabe is a navigational instrument that allowed sailors to measure the angle of the sun or a star above the horizon.

This astrolabe was made in 1555 by Lopo Honem, a Portuguese instrument maker. During the 1600s it came into the possession of Andrew Smyton who was a Dundee ship owner engaged in the salt trade with France.
