CANT, Arent (1695-1723). Impetus primi anatomici ex lustratis cadaveribus nati. Leiden: Peter van der Aa, 1721. 2o (504 x 372 mm). Engraved title vignette, 6 engraved plates, on extended guards (some dampstaining at end, a few tears and chipping to some margins, outer blank margin of plate 6 repaired). Contemporary calf, spine gilt (spine ends and corners repaired). Provenance: Ira M. Rutkow (pencil signature on rear flyleaf). FIRST EDITION. Cant, a pupil of Frederik Ruysch, was a skilled anatomist and artist whose ambitious plan to publish a great anatomical work was prevented by his premature death at the age of 28. This is the only volume of Cant's projected anatomy; it contains six large folding plates, drawn by the author, illustrating the anatomy of the head, heart, stomach, shoulder and knee joints, thoracic duct, etc. Cant was one of the few early anatomists to make use of the "grid-reference" identification system devised by Eustachi, in which anatomical structures are located by means of numbered borders at the side and top of each plate; this method allows the anatomist to illustrate his figures without superimposed lettering or numbering.
