[John Dee’s motivations were not much different from Faust’s:]
‘A student of the Renaissance Neo-Platonism of Marsilio Ficino, Dee did not draw distinctions between his mathematical research and his investigations into Hermetic magic, angel summoning and divination. Instead he considered all of his activities to constitute different facets of the same quest: the search for a transcendent understanding of the divine forms which underlie the visible world, which Dee called “pure verities”.’Pasted from <https://en.wikipedia.org/wiki/John_Dee> “Dee, on the other hand, was more interested in communicating with the angels whom he believed would help him solve the mysteries of the heavens through mathematics, optics, astrology, science and navigation.”Pasted from <https://en.wikipedia.org/wiki/John_Dee#Final_years>
