Summary: Astronomical instrument from medieval Spain which could perform multiple tasks, from working out the time to preparing horoscopes. Originating from Spain at a time when Christianity, Islam and Judaism coexisted there, this instrument carries symbols recognisable to all three religions. Neil MacGregor, Director of the British Museum, considers who it was made for and how it was used. Historian Sir John Elliott discusses the political and religious climate of 14th-century Spain.
