A handsome (likely) contemporary binding houses this wonderful practical mathematics work from The Enlightenment, filled with thirty-seven fold-out plates illustrating the instruments and concepts discussed. This is a well-regarded work, and the fourth edition (here) was expanded with additional information. This copy has some notable scientific provenance.
Details from the Erwin Tomash Library -
“Nicholas Bion was the king’s engineer for mathematical instruments. It is surprising how little is known about his life beyond the fact his workshops were in Paris. His name is very well known, but it is difficult to determine if his fame rests on the quality of his instruments or on this respected work. Only a few of his original instruments appear to have survived.”
“The work is encyclopedic and gives descriptions of the mathematical instruments commonly available at the beginning of the eighteenth century. Bion interpreted mathematical broadly, for the work contains information on devices used in a variety of scientific and engineering fields. It is composed of a preface giving definitions of mathematical terms, followed by eight separate books:
1. rulers and protractors
2. the sector: containing a line of equal parts (“B” in his figure 1), line of planes (“C”), line of polygons (“D”), line of chords (“F”), line of solids (“H”) and line of metals (“G”).
3. the compass (including both proportional compass and beam compass)
4. surveying devices (quadrants, chords, chains and sighting devices)
5. water levels and gunner’s instruments (gunner’s compass and quadrant)
6. astronomical instruments (large quadrants and micrometers for measuring)
7. navigational instruments, including, for example, the Jacob’s staff and the mariner’s quadrant, which were, by then, no longer in use
8. sundials of all forms at all orientations, the nocturnal and a water clock”
About the Fourth Edition -
“This fourth edition was published after Bion’s death in 1733, the printing being supervised by his son. It uses the same frontispiece as the second edition (1716) but also includes an idealized engraved portrait of Bion—done posthumously (c. 1740) by De Larmessin, the King’s engraver. The content of the second edition has been further augmented with an additional chapter to Book 6 on octants and other astronomical instruments; two very small additions to Book 7 (dignified by being given their own chapter); and a completely new Book 9, which describes a miscellaneous collection of devices from water pumps to burning glasses.” - Tomash Catalog
The first blank unpaginated endpaper has a catalog number from E. Weil (1059 10633) a noted rare book dealer focused on scientific works in the early 20th century.
This copy also resided in the Erwin Tomash Library (evidenced by his ticket on the pastedown), which focused on the History of Computing (many of the books were sold on at his passing).
