Mathematics, navigation and empire: reassessing John Dee’s legacy

John Dee (1527-1609) was a philosopher and scholar whose work during the Tudor period has been overshadowed by his alleged sorcerous and occultist activities. He is best known for having conversations with angels through his scryer Edward Kelley's interests in astrology, alchemy, calendar reform and suggesting the date for Queen Elizabeth's coronation. What John Dee may not be as well known for is his influence on English navigation and being the first person to coin the term 'British Empire'.
