Engraved by Louis de Chastillon after Nicholas Robert Imperial folio. Platemarks each approx. 450 x 300 mm. (15 3/4 x 11 3/4 in), sheets approx. 540 x 38 mm.. On beautiful 18th Century laid paper with the watermark sadly indecipherable.. Issued in the exceptionally rare series: Estampes pour servir l’Histoire des Plantes by Nicholas Robert, Paris 1719-1786? The plates are 17th Century and issued at some time up to 1786. With the blind stamp to the lower margin of the ‘Calcographia du Louvre’ indication a later impression. Plates by or after Nicolas Robert represent work by the greatest botanical artist of the seventeenth century. The work was never published or offered for public sale, and the present plate was probably given as a Royal gift some time between 1719 and about 1786. "The original idea for this encyclopaedic undertaking was conceived by Perrault and the proposal was enthusiastically received by Colbert, minister to Louis XIV, although it appears to have actually begun to take shape only when the botanist Denis Dodart (1634-1707) joined the Academie in 1673. His work, Memoires pour servir a l'Histore des Plantes, which was intended to form the introductory volume to this series, appeared in 1675 and contained thirty-nine plates by Robert. In it Dodart lamented the fact that none of the engravings could be in colour, but at least, he assured the reader, all the illustrations in the new series would be drawn directly from life, the artist making every effort to present the plants in their actual dimensions" (Lucia Tongiorgi Tomasi An Oak Spring Flora p 168). Louis de Chatillon (1639-1734), continued the work after Robert's death in 1684.
