Thomas Digges
Thomas Digges entered the world around 1546. His father Leonard Digges worked as a mathematician and surveyor. Bridget Wilford served as his mother. She was the daughter of Thomas Wilford, an esquire from Hartridge in Cranbrook, Kent. This family connection placed young Thomas within the gentry class of Elizabethan England. He had two brothers named James and Daniel. Three sisters also filled out the household. Mary married a man with the surname Barber. Anne wed William Digges. Sarah first married a man surnamed Martin before marrying John Weston.
The death of his father changed everything for the boy. Leonard Digges died around 1559. Thomas grew up under the guardianship of John Dee. Dee stood as a typical Renaissance natural philosopher during that era. The relationship between the orphaned son and the famous scholar shaped the future direction of Thomas's life. Dee provided guidance through the turbulent years following his father's passing.
In 1576, Thomas Digges published a new edition of his father's perpetual almanac titled A Prognostication everlasting. The text written by Leonard Digges for the third edition of 1556 remained unchanged. Thomas added new material in several appendices to this work. The most important addition carried the title A Perfit Description of the Caelestiall Orbes according to the most aunciente doctrine of the Pythagoreans, latelye revived by Copernicus and by Geometricall Demonstrations approved.
This appendix featured a detailed discussion of the controversial and still poorly known Copernican heliocentric model of the Universe. It marked the first publication of that specific model in English language history. The work served as a milestone in the popularisation of science across England. For the most part, the appendix functioned as a loose translation into English of chapters from Copernicus's book De revolutionibus orbium coelestium. Thomas Digges went further than Copernicus however. He proposed that the universe is infinite. This proposal contained infinitely many stars at varying distances. He may have been the first person to do so, predating Giordano Bruno's views in 1584 and William Gilbert's views in 1600.
He attempted to determine the parallax of the supernova observed by Tycho Brahe in 1572. His conclusion stated that this celestial event had to occur beyond the orbit of the Moon. This finding contradicted Aristotle's view of the universe. Aristotle held that no change could take place among the fixed stars. The observation of the new star challenged centuries of established philosophical thought about the heavens.
In 1583, Lord Burghley appointed Thomas Digges along with Henry Savile and John Chamber to sit on a commission. Their task involved considering whether England should adopt the Gregorian calendar as proposed by John Dee. Britain did not actually adopt the calendar until 1752. This delay highlights how slowly scientific reforms moved through English institutions during the Elizabethan era.
Digges served as a member of parliament for Wallingford. He also maintained a military
career as a Muster-Master General to the English forces from 1586 to 1594. This period coincided with the war with the Spanish Netherlands. In his capacity as Master-Muster General he was instrumental in promoting improvements at the Port of Dover. These duties required him to balance astronomical study with practical statecraft and defense logistics.
His influence extended into the next generation through his children. He named two surviving sons, Sir Dudley Digges who became a politician and statesman, and Leonard Digges who became a poet. Two surviving daughters named Margaret and Ursula also carried forward his lineage. The work he published in 1576 remained the first publication of the Copernican system in English. It helped popularize science during a time when such ideas faced significant resistance from
traditional authorities.
