The name Blagrave is mentioned every day in the town of Reading in Berkshire, in one of its streets, on buses and even in the name of one of its pubs. But few people know where it originally came from and why it's remembered today.
John Blagrave, one of the more famous of Reading's historic residents, was born to parents Anne and John Blagrave from Sonning. After taking the education expected of a wealthy young teenager, he developed a special curiosity for mathematics and mathematical instruments. At his home in Southcote Lodge he spent hours researching, experimenting and writing, publishing The Mathematical Jewel in 1585, with the wordy subtitle: 'shewing the making and most excellent use of a singuler instrument so called, in that it performeth with wonderfull dexteritie whatever is to be done either by Quadrant, Ship, Circle, Cylinder, Ring, Diall, Horoscope, Astrolabe, Sphere, Globe, or any such like heretofore devised’. In 1590 he published his Baculum Familliare Catholicon sive Generale. This book shared his new invention with the world: a 'familiar staffe', which could be carried along as you walked, and calculated 'geometrical mensurations of all altitudes'. By 1596, he was inspired by the long voyages carried out by Elizabeth I's sailors across the globe, titling his next work Astrolabium Uranicum Generale: a necessary and pleasaunt solace and recreation for Navigators in their long jorneying. After Elizabeth's death, he continued working into the reign of James VI and I, publishing The Art of Dyalling, in two parts, in 1609.

On his death in 1611, John left no children of his own, but bequeathed lands in Southcote to multiple family members, it being estimated that up to 80 people benefited from his generosity. He also left a sum of 20 nobles to be given to one woman in Reading each Easter, to help with her personal circumstances. He stipulated though, that she should be of good character and have already completed five years' service to a master of the town. John clearly preferred to help those who were hard-working and trustworthy. The women applied through a process like an election, where they would petition for their right to the cash, with the council considering each application. No doubt many seventeenth-century women benefited immensely from the funds that John left.
After more than 20 years of mathematical enquiry, John Blagrave died on 9 August 1611 and was buried in St Laurence's Church in the marketplace of Reading. His memorial effigy can be seen on the wall inside. It is very similar to that of William Shakespeare in Stratford Upon Avon in design. John is standing (or is seated?) upright, from the waist up, looking out at us and holding mathematical instruments in each hand. It is an early Renaissance-style English effigy memorial, crafted with flourishes, scrolls and painted with accents of gold. Two skulls hover on each side, warning us that death will come for us, too - while figures clad in classical togas hold geometric shapes and lounge on the pillars and structures around him.
The inscription reads:
Here lyes his corpes which living had a spirit, Wherein all worthy knowledge did inherit, By which with zeal our God he did adore, Left for maidservants and to feed the poore, His virtuous mother came of worthie race, A Hungerford and buried neere this place, When God sent death their lives to call, They lived beloved and dyed bewayld of all. Deseased the 9th of August Anno Domino MDCXI.
John Blagrave was a Renaissance man who helped define his era. He was preoccupied with learning, dedicating hours to the study of new ideas in mathematics and the invention of mechanical instruments. He published works to help spread these ideas and allow people to build on them. Much in the same way too, that the early Medicis of Florence ploughed state money back into public buildings and art, John allocated funds of his own for the relief of the poor and divided up his estate so that many people could benefit from his accrued wealth rather than just one or two people. It is not clear whether he directed the design of his memorial in St Laurence's, but it has clear visual accents of the era: geometric shapes, figures resembling those of classical antiquity and features a number of different mathematical instruments he would have used, and even invented. Not to be forgotten, John Blagrave changed lives in Reading as well as further afield, and contributed to the study of one of the growing disciplines of the seventeenth century.

My book, Power Couples of the Renaissance, examines this era and explores the relationship dynamics that went against accepted norms of the period. There were also power-hungry couples who ruled, fought and spread the patronage of art, science and culture across the globe during one of the most tumultuous periods of history.
