Francis Moore was an astrologer, licensed physician and Whig partisan, who had an astrological practice in Lambeth, and later in Southwark. His Vox Stellarum, an Almanac for 1701 with astrological observations appeared in 1700. Old Moore’s Almanack long outlived its creator, and sold extremely well throughout the 18th and 19th centuries, and it still thrives thanks to its reputation for sensationalism and prophecy; its print order in 1975 ran to one and three-quarter million copies. There have been claims that it predicted the 9/11 attacks of 2001.
