BRIGGS, Henry [GELLIBRAND, Henry]
Trigonometria Britannica: sive De doctrina triangvlorvm libri dvo. Presented by Gellibrand to John Bainbridge, with numerous mathematical annotations by Abraham Sharpe
Gouda: Pieter Rammazeyn, 1633. First edition of the first complete set of tables of sines, tangents, secants and their logarithms. This is a historically important copy presented by Gellibrand (1597-1636), who completed the work after Briggs' death in 1630, to the English astronomer John Bainbridge (1582-1643), noted particularly for his work on comets. It was later owned by the Yorkshire mathematician and astronomer Abraham Sharpe (1653-1742), and has his numerous, detailed mathematical annotations throughout the text and the tables (often very extensive). Sharpe served as assistant to the Astronomer Royal John Flamsteed and edited the latter's 'Historia coelestis' (1712). It is probable that Sharpe used this copy of the Trigonometria in computing the tables in Flamsteed's work. Briggs (1561-1630) was a key figure in early English science, being at the centre of a group that included William Gilbert, Edward Wright, Thomas Blundeville, Aaron Rathborne, Mark Ridley, Robert Hues, Hackluyt, and John Pell among others. Briggs was perhaps the first person, after their inventor John Napier, to realise the importance of logarithms, and following visits to Napier in 1615 and 1616 convinced him to use base 10 (Napier had originally used as base 1/e, where e is the base of 'natural logarithms'). In 1617, shortly after Napier's death, Briggs published 'Logarithmorum Chilias Prima,' which contained the first table of base 10 logarithms (of numbers from 1 to 1,000). For the next several years, Briggs devoted himself to the time-consuming and laborious task of constructing a larger table … [Click Below for Full Description]
