John Dee was a renowned 16th century mathematician, writer, astronomer, astrologer and occult philosopher in England. He was well-known for being an advisor to Queen Elizabeth I. A major part of his life was dedicated to the study of alchemy, occultism and divination. Born into an affluent household, he studied at prestigious institutions across Europe and gained knowledge under the apprenticeship of several mathematicians and cartographers. After acquiring the patronage of the English monarch, he is said to have coined the phrase ‘British Empire’ when he advised the queen to claim foreign lands for Britain via maritime supremacy. He then focused his attention on communicating with angels and reading the future, with the aid of the medium, Edward Kelley. He studied many subjects during his lifetime and made significant advances in each field. He also authored several books on mathematics, scientific and occult subjects. Towards the end of his life, he was shunned by the monarchy and died in abject poverty. He was a family man, but sadly outlived most of his children. Several books, plays and characters have been inspired by him.
