    More Information:

    Partridge, John (1644-1715), astrologer and almanac writer. In the main, however, Partridge's energies in this decade were devoted to astrological battles. He was the acknowledged leader of a programme to reform astrology, which he viewed as corrupted (also a whig and republican theme), and which he intended to restore to its former glory by "Reviving the True and Ancient Method laid down for our Direction by the Great Ptolemy." He announced his aim in Opus reformatum (1693). For Partridge and his principal ally, John Whalley, Ptolemy had provided something very like the equivalent of the whigs' "Ancient Constitution" for astrologers.


    This reform project recognized the disrepair and sinking estate of astrology in England since 1660. It placed the blame on the popular, magical, and ostensibly decadent practices of "Magick-Mongers, Sigil-Merchants, Charm-Broakers, &c." (J. Partridge, Defectio geniturarum, 1697, BV). The remedy, according to Partridge, was a reform of astrology along strictly rational lines, as "no otherways than as a Branch of Natural Philosophy" (Opus reformatum, 1693, viii) not in the sense adhered to by the Royal Society, but rather using principles of "Motion, Rays, and Influence" (ibid.) formulated in the Aristotelian tradition, mathematically adumbrated, and resulting in precise (and indeed, testable) predictions... Partridge's next book was duly entitled Defectio geniturarum (1697), "Being an Essay toward the Reviving and Proving the True Old Principles of Astrology." It attacked Gadbury as an "ignorant Reformer" along with his data, his methods of interpretation, his colleague George Parker, the innovations of Kepler, and the heliocentric astrology with which several of the Baconian reformers had experimented. Instead Partridge offered a narrowly internal, puritanically pure, and thoroughly traditional astrology, rational and naturalistic in the Aristotelian sense. There is no mistaking his sense of urgency: "never did Astrology stand in need of a speedy Reformation more than at this time É Astrology is now like a dead Carkass" (Defectio geniturarum, B2R)


    Partridge continued the dispute with an attack on Parker in Flagitiosis mercurius flagellatus (1697), in which he accused Parker of wife-beating, adding that he "whipped her too the heliocentric way" (p. 28). Parker returned the favour, asserting (for example) in his almanac for 1706 that Partridge's real family name was Hewson, and calling him "a Junior Hewson" (Mayhew, 41), clearly a reference to Colonel John Hewson (d. 1662), a particularly ruthless soldier and judge under Cromwell, also originally a cobbler, who was still remembered in the early eighteenth century. (But not, it seems, by a later biographer of Partridge, Bishop Thomas Percy of Dromore, writing in The Tatler in 1786, who took Parker's reference literally.)

    Partridge's programme to rescue astrology was a failure. The sharp decline in respect for that subject was due to political developments and broad social changes, especially since about 1660, which were quite out of the control of any individual astrologers and any merely internal reform. His Ptolemaic astrology was taken into the early nineteenth century by John Worsdale, with equal rigour but equal lack of general acceptance. [ODNB]
