Astrolabe
This device is thought to have been first developed by the ancient Greeks, the term astrolabe meaning ‘star taker.’ It is a primitive inclinometer that calculates the altitude of the sun and stars to determine latitude. An astrolabe can be used for both astronomy and navigation at sea. Elaborate astrolabes can have etchings of how the sky looks at any given time or season. Sailors used this device by lining it up with the sun or a specific star, such as the North Star, in relation to the horizon in order to measure latitude vertically. This helped sailors to determine their location while at sea. Astrolabes came in a variety of shapes, such as a sphere or as flat plates and disks, and were made of metal, usually brass or iron, the former ensuring longevity at sea. A disadvantage was that astrolabes were cumbersome and could be difficult to use on the rolling deck of a ship.…

His name was first anglicised to Henry when he was knighted in 1674. However, not much else is known about his early life.…
