First edition. NAPIER'S BONES THE FIRST MECHANICAL CALCULATING DEVICE AFTER THE ABACUS . First edition, very rare, of the first mechanical calculating device after the abacus, using little rods of wood or ivory now known as 'Napier's bones'. Napier is best known today for his invention of logarithms, published in 1614 as Mirifici logarithmorum canonis descriptio, the most important aid to calculation before the advent of mechanical and electronic calculators in the twentieth century. In fact, Napier's bones and logarithms both achieve the same aim - they reduce multiplication to addition. "In 1617 Napier's intense concern for the practicalities of computation led him to publish another book, the Rabdologiae, which contains a number of elementary calculating devices, including the rods known as 'Napier's bones.' These rods, which in essence constitute a mechanical multiplication table, had a considerable vogue for many years after his death. Each rod is engraved with a table of multiples of a particular digit, the tens and units being separated by an oblique stroke. To obtain the product 267 × 8, the rods 2, 6, 7 are assembled and the result is read off from the entries in the eighth row [adding the numbers in the small parallelograms formed by the three rods]; this gives 2,136. Book II is a practical treatment of mensuration formulas. Book III, the method of the promptuary, deals with a more complicated system of multiplication by engraved rods and strips, which has been called the first attempt at the invention of a calculating machine. The concluding section deals with a mechanical method of multiplication that was based on an 'areal abacus' consisting of a checkerboard with counters, in which numbers were expressed in the binary scale" (DSB). In this last section, Napier was one of the first to use the decimal point - according to Goldstine (The Computer from Pascal to Von Neumann, p. 4), he "was perhaps the first man to understand, in his Rabdologia in 1617, the use of the decimal point in arithmetical operations" (Goldstine, p. 4). The name 'Napier's bones' appears to have originated from the title of a work by William Leybourn published in 1667 entitled The art of numbering by speaking rods: vulgarly termed Napier's bones. Leybourn's use of the term 'speaking rods' was a mistranslation of the title of Napier's Rabdologia - this comes from the Greek 'rabdos' meaning a 'rod' and 'logia' meaning 'collection', and not, as Leybourn thought, 'logos' meaning 'word'. Provenance: Inscribed "Del Cav.re Franc. Ma. Naldini" on the title-page and "Ex Libris Equitis Francisci Mariae Naldini" on the front flyleaf, i.e., Francesco Maria Naldini (d. 1692), Cavaliere di Santo Stefano, of the Naldini del Riccio family of Prato and Florence. Archival sources document his Studi matematici (1668-1676) and Studi di astronomia (1681-1688), together with letters to the librarian and scholar Antonio Magliabechi, attesting to his close engagement with contemporary mathematical and astronomical inquiry. The Naldini family papers also record the grand-ducal patent conferring his knighthood in 1668 and mention his study of scientific instruments and books, particularly those concerning geometry and celestial measurement. The same ownership inscriptions, combining a Latin ex-libris on the front guard and an Italian form on the title, appear in other volumes known from his library, notably a copy now at the University of Pisa dated 1672. "John Napier, Baron of Merchiston, was born in 1550 just as the Scottish Reformation was starting. He is best known for his invention of logarithms, but he spent a large part of his life devising various other schemes, both mechanical devices and logistical practices, for easing the labor involved in doing arithmetic. He undoubtedly used these devices in the calculation of his first table of logarithms. The best known of these devices is his Rabdologia, or as they are more commonly known, Napier's rods or Napier's bones. The name bones arose from the fact that the better quality sets were constructed from horn, bone, or ivory. Various authors have preferred to call them numbering rods, multiplying rulers, or even speaking rods, but the name bones has lasted. Today the bones are considered a mere curiosity while his other two devices have been almost entirely forgotten. The Promptuary of Multiplication was simply a modified version of his bones that, at the expense of being more difficult to construct, eliminated some of the problems of multiplying one multi-digit number by another. It was an interesting idea but never became popular. The local arithmetic device was simply a standard chess or checkerboard used as a modification of the table abacus. Each row and column represented a power of two higher than the one below or to the right. Again, it was never really used by the public because of the seemingly unnatural use of binary numbers. Napier did not at first consider these inventions worthy of publication; however, several friends, particularly Alexander Seton, the Earl of Dunfermline and High Chancellor of Scotland, pressed him to write them up, if only to avoid having others claiming them as their own. His descriptions appeared in a small book entitled Rabdologia in the year of his death and three years after the publication of his description of logarithms. "The idea for the bones undoubtedly came from the gelosia method of doing multiplication. This ancient method probably originated in India and spread to Arab, Persian and Chinese societies by the late Middle Ages. The method was introduced sometime in the fourteenth century into Italy, where it obtained its name from its similarity to a form of Italian window grating. "The method consists of writing down a matrix like grid, placing one digit of the multiplicand at the head of each column and one digit of the multiplier beside each row; the product of each row and column digit was then entered in the appropriate box of the matrix-the te.…
