Briggs was the founding professor of geometry in 1596 at the newly created Gresham College, and in 1619 was appointed to the professorship of geometry in Oxford. In this work he first used 10 for the base of his tables of logarithms. These logarithms, together with those of Adriaan Vlacq, form the basis from which almost all other logarithm tables were produced.
This copy does not have additional six leaves found in some copies (for which see lot 92), which were printed a few years later (in 1628) in Gouda by Rammezeyn.
