William Parron (b. c. 1460, fl. 1500) was an Italian astrologer, who worked for Henry VII of England from 1498 to 1503.[1] An author of almanacs and prognostications, he produced the De astrorum vi fatali in 1499 as a private printed prediction for Henry.[2] He also engaged in investigative work on the background of Perkin Warbeck.[3]
His publishers were Wynkyn de Worde and Richard Pynson, and the almanac is said to be the first printed in English.[4] The almanac for the year 1500 survives to this day.[5][6] However, Parron's prediction that Henry's queen would live to age 80 backfired, as she died young. Parron subsequently left the court.[7][8]
