pp. 323. 5 plates. 4to. The following entry is taken from a Quaritch catalogue of 1981: 74. EULER, Leonhard. Methodus inveniendi [etc.] 4 to, with the first blank, 5 folding engraved plates; a fine copy in nineteenth century boards, joints split. Marc Michel Bousquet, Lausanne and Geneva, 1744. $3,250 First edition. The first formulation of the principal problems of the calculus of variations, perhaps Euler’s most important original contribution to mathematics. Commentators and collectors do not agree on which of Euler’s mathematical works is the most significant, although citations in the catalogues of “best books” must be based to some extent on what could be obtained. “Printing and the mind of man” and Sparrow, “Milestones of science, list his “Introductio in analysis infinitorum”, 1748, but Dibner, “Heralds of science” and Horblit, “One hundred books famous in science” and Evans, “Epochal achievements” cite the present work. Bell in his “Men of mathematics”, comments: “His great treatise of 1748, 1755 and 1768–70 on the calculus…instantly became classic and continued for three- quarters of a century to inspire young men who were to become great mathematicians. But it was in this work on the calculus of variations…that Euler first revealed himself as a mathematician of the first rank. Dibner 111; Horblit 28; Evans 9. [In MS] Quaritch Cat. 1018 Oct. 1981
