William Lilly (April 30, 1602-1681), was a very well-known English astrologer and occultist during his time. Lilly was particularly adept at interpreting the astrological charts drawn up and used in horary astrology, as this was his specialty. He caused much controversy in 1666 for alledgedly predicting the Great Fire of London some 14 years before it happened. Because of this many people thought that he in fact may have started it, but there is no evidence to support these claims.

He was born in 1602 at Diseworth in Leicestershire, where his family were long-established yeomen. He received a basic classical education at the school of Ashby-de-la-Zouch, but makes a point of saying that his master never taught logic. At the age of seventeen, his father having fallen into poverty, he went to London and was employed in attendance on an elderly couple. His master, at his death in 1627, left him an annuity of £20; and, Lilly having soon afterwards married the widow, she, dying in 1633, left him property to the value of about £1000.

He now began to dabble in astrology, reading all the books on the subject he could fall in with, and occasionally trying his hand at unravelling mysteries by means of his art. The years 1642 and 1643 were devoted to a careful revision of all his previous reading, and in particular, having lighted on Valentine Naibod 's Commentary on Alcabitius , he "seriously studied him and found him to be the profoundest author he ever met with." About the same time he tells us that he “did carefully take notice of every grandaction betwixt king and parliament, and did first then incline to believe that as all sublunary affairs depend on superior causes, so there, was: a possibility of discovering them by the configurations of the superior bodies." And, having thereupon "made some essays," he "found encouragement to proceed further, and ultimately framed to himself that method which he ever afterwards followed."

Lilly's most comprehensive book was published in 1647 and was entitled Christian Astrology. It was so large that it came in three seperate volumes, and it remains popular even today and has never gone totally out-of-print. It is considered one of the classic texts for the study of traditional astrology from the Middle Ages.

He then began to issue his prophetical almanacs and other works, which met with serious attention from some of the most prominent members of the Long Parliament. If we may believe his statements, Lilly was on intimate terms with Bulstrode Whitlock , William Lenthall the speaker, Sir Philip Stapleton , Elias Ashmole and others. Even John Selden seems to have acknowledged him, and probably the chief difference between him and the mass of the community at the time was that, while others believed in the general truth of astrology, he ventured to specify the future events to which he referred.

Even from his own account, however, it is evident that he did not trust implicitly to the indications given by the aspects of the heavens, but kept his eyes and ears open for any information which might make his predictions safe. It appears that he had correspondents both at home and in foreign parts to keep him conversant with the probable current of affairs. Not a few of his exploits indicate rather the quality of a clever police detective than of a profound astrologer.

After the Restoration he very quickly fell into disrepute. His sympathy with the parliament, which his predictions had generally shown, was not calculated to bring him into royal favour. He came under the lash of Butler, who, making allowance for some satiric exaggeration, has given in the character of Sidrophel a probably not very incorrect picture of the man; and, having by this time amassed a tolerable fortune, he bought a small estate at Hersham in Surrey, to which he retired, and where he diverted the exercise of his peculiar talents to the practice of medicine. He died in 1681.

Lilly's life of himself, published after his death, is still worth looking into as a remarkable record of credulity. So lately as 1852 a prominent London publisher put forth a new edition of Lilly's Christian Astrology, "with numerous emendations adapted to the improved state of the science."
