Source: MHS

Thomas Gemini (originally ‘Lambrit’) was a Flemish engraver, printer, map- and instrument-maker who had trained at Louvain, very possibly under Mercator. He came to England in c.1540 and established a workshop in London. This astrolabe, which was made for Elizabeth I, can be compared with the one from Louvain by Arsenius. It follows a similar arrangement of combining the standard astrolabe on one side with Gemma’s universal or ‘catholic’ astrolabe on the other, and also contains a nautical quadrant, again following Gemma’s pattern.
