More about William Leybourn

Recently received a cloth-covered book called 'Leybourn's Plans of London Markets, 1677' written by Betty Rowena Masters in 1974.

It was interesting that I did not pay attention that this Leybourn is the same Leybourn in Susanna Gregory's fiction but just causally placed order because it is about public markets in 17th century's London. Before placing order, I have already learned the name 'William Leybourn' which appears many times in the fiction. What an absent-minded person I am!

Introduction about William Leybourn written by Masters:
"William Leybourn (1626-1716) was one of the band of distinguished surveyors who in the years following the Great Fire of London were engaged in the service of the City and in the multifarious tasks of rebuilding. Like Robert Hooke, John Oliver and the others, Leybourn's interests and activities were wide ranging. He began his career as a printer and, in partner with Robert Leybourn, possibly a brother, he printed between 1645 and 1665 many scientific and mathematical books. He was himself the author of many books, on land surveying, logarithms, navigation, mathematical and surveying instruments, and astronomy; he produced a ready reckoner; and he advertised himself as a teacher of the mathematical sciences, a surveyor of land, a measurer of buildings and a maker of sundials. A number of Leybourn's books went to several editions, and his most influential work on surveying, The Complete Surveyor, first published in 1653, passed through four editions in the author's lifetime and a fifth in 1722." (The Public Markets of the City of London surveyed by William Leybourn in 1677, p.9)
