Llanberis, Gwynedd

Mathematical Gazetteer of the British Isles


In the Quarry Hospital (Llanberis Miners' Hospital) is displayed a fireplace whose carved decoration was designed by John Thomas (1805-1840), schoolmaster, author of textbooks and almanacs in Welsh and Chief Computor at Greenwich Observatory at the time of his death. The design shows diagrams of eclipses of both sun and moon, the solar system, the orbit of Halley's comet, etc. [1] [2]
