Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In 1617 a treatise in Latin entitled Rabdologiæ and written by John Napier was published in Edinburgh. Printed three years after his treatise on the discovery of logarithms and in the same year as his death, it describes three devices to aid arithmetic calculations. The devices themselves don''t use logarithms, rather they are tools to reduce multiplication and division of natural numbers to simple addition and subtraction operations. The first device, which by then was already popularly used and known as Napier''s bones, was a set of rods inscribed with the multiplication table. Napier coined the word rabdology (from Greek o [rabdos], rod and o o [logos] calculation or reckoning) to describe this technique. The rods were used to multiply, divide and even find the square roots and cube roots of numbers.
