NEWTON ISAAC (1642-1727)
Autograph MANUSCRIPT; 1 page oblong in-8 format (dimensions: 10,5 x 15,2 cm), framed with an engraved portrait; in english.
Mathematical calculations, probably ties to the price of gold.
This leaf contains about fifteen lines of mathematical calculations, likely relative to the price and value of gold, beginning with divisions and subtractions, followed by three separate lines:
Value 1/5 of a coin of 8; Value 1/5 – 1/250=1/5 1/11; Value 10 3/5 11 ½
Above are other operations and calculations.
These calculations are tied to Nexton’s association with the Royal Mint where he was hired first as Warden (1696) and after as Master (1699). He contributed a lot to reform the institution, at its worst at the time, and participated in the increase of the currency at a time when the scarcity of currency could stall commercial exchanges. The reference here to coins of 8 and the proportional calculations offered here are ties to that period of work ensured by Newton.
