[105] The diffusion and progress of astrology in the last two centuries before the Empire, in Greece and Italy, was favoured chiefly by the four following causes: its resemblance to the meteorological astrology of the Greeks; the belief in the conversion of the souls of men into stars; the cessation of the oracles; the belief in a tutelary genius.--Sir G. C. Lewis's _Historical Survey of the Astronomy of the Ancients_, chap. v. The life of Dr. Dee, an eminent Cambridge mathematician, and of his associate Edward Kelly, forms a curious biography. Dee was born in 1527. He studied at the English and foreign universities with great success and applause; and while the Princess Elizabeth was quite young he acquired her friendship, maintained by frequent correspondence, and on her succession to the throne the queen showed her good will in a conspicuous manner. John Dee left to posterity a diary in which he has inserted a regular account of his conjurations, prophetic intimations, and magical resources. Notwithstanding his mathematical acumen, he was the dupe of his cunning subordinate--more of a knave, probably, than his master. In 1583 a Polish prince, Albert Laski, visiting the English court, frequented the society of the renowned astrologer, by whom he was initiated in the secrets of the art; and predicted to be the future means of an important revolution in Europe. The astrologers wandered over all Germany, at one time favourably received by the credulity, at another time ignominiously ejected by the indignant disappointment, of a patron.[106] Dee returned to England in 1589, and was finally appointed to the wardenship of the college at Manchester. In James's reign he was well received at Court, his reputation as a magician increasing; and in 1604 he is found presenting a petition to the king, imploring his good offices in dispelling the injurious imputation of being 'a conjuror, or caller, or invocator of devils.' Lilly, the most celebrated magician of the seventeenth century in England, was in the highest repute during the civil wars: his prophetic services were sought with equal anxiety by royalists and patriots, by king and parliament.[107] Sometimes the professor of the occult science may have been his own dupe: oftener he imposed and speculated upon the credulity of others. [106] While traversing Bohemia, on a particular occasion, it was revealed to be God's pleasure that the two friends should have a community of wives; a little episode noted in Dee's journal. 'On Sunday, May 3, 1587, I, John Dee, Edward Kelly, and our two wives, covenanted with God, and subscribed the same for indissoluble unities, charity, and friendship keeping between us four, and all things between us to be common, as God by sundry means willed us to do.' A sort of inspiration of frequent occurrence in religious revelations, from the times of the Arabian to those of the American prophet.
