H107 Nautical Astrolabe

It is the simplification of the planispheric astrolabe. Through the experience of the navigators it acquired its definitive form. Measuring the height of the stars it obtains the Latitude.

This Portuguese nautical astrolabe (1550-55) was owned by the skipper of a small Dundee ship, A. Smyton. The original is in the Art Gallery and Museum in Dundee, Scotland.
