Gunter's Rule by Rabone, London
In 1620 Edmund Gunter (1581-1626) in London made a linear logarithmic scale and performed multiplication and division on it using dividers to add and subtract distances.
He was a contemporary of John Napier, who in 1614 published the first table of logarithms.
Gunter rules have many scales, but the revolutionary one is named NUM and has the numbers from 1 to 100 laid out in a two cycle logarithmic scale.
Due to the speed of calculations it allowed, Gunter's scale was used well into the 19th century.
It was the immediate predecessor of the slide rule, created by William Oughtred shortly after, who used two Gunter scales side by side to add lengths without dividers and read results directly.
