Extremely sought after double page engraving of one of the first mechanical ancestors of computers! Although certainly closer to an analog computer than a digital computer, but clearly authentic piece of hardware, and giving a mechanical implementation of an algorithm known as optimal for the calculation of a polynomial. And yet, it was never made...

Tall folio engraving issued in the rare supplement of Diderot’s famed Encyclopédie, ou dictionnaire raisonné des sciences, des arts et des métiers.. 1777.

The overall size is ca. 46 x 31 cm. The image size is ca. 35 x 24 cm. 

Published in Paris.

Superb original from the preferred large folio edition. Light staining to outer lower margin. A few minor age spots.
