*GROTIUS (Hugo). Dissertationes De Studiis instituendis. Amsterdam: Louis Elzevier, 1645. - In-12, 143 x 75 : (6 ff.), 687 pp. Dark blue morocco, double framed with gilt and cold filets with gilt fleuron on the corners of the boards, spine decorated with gilt and cold motifs, interior gilt filets, parchment endpapers, untrimmed, half black morocco slipcase (Simier R. du roi for the binding and James Macdonald in New York for the slipcase). Willems 1028. edition published the same year as the one given by Louis Elzevier in Amsterdam, printed in the same city by Joan Blaeu . It has the same engraved title but a different pagination. We repeat what Willems says about this book. It is an "interesting collection, comprising twenty-four essays on the best method to follow in the study of letters and sciences. Composed by judges as competent in the matter as the Grotius, the Naudé, the Erasmus, the Barlæus, the Campanella, &c., these dissertations contain a quantity of ingenious and practical views. A precious copy with full margins, bound by Simier and with prestigious origins. It would have come primarily from the library of the publisher and bibliophile Antoine-Augustin Renouard (1765-1853), for whom the binding was made. The presence of parchment endpapers is one of the clues to this provenance. It later came into the possession of the great American bibliophile Mortimer Leo Schiff (1877-1931) who had the binding done by the New York bookbinder James Macdonald (1859-1920), then of the English bibliophile John Hely-Hutchinson (1881-1955) and of Charles Van der Elst, president of the Société des bibliophiles et iconophiles de Belgique. A perfectly preserved copy. Provenance: Antoine-Augustin Renouard. - Mortimer Leo Schiff, with ex-libris (cat. December 1938, n° 1597). - John Hely-Hutchinson, with ex-libris (cat. 1956, n° 326). - Charles Van der Elst, with bookplate (cat. I, 1985, n° 99).
