First edition of the work which created the calculus of variations. This book, which displayed “an amount of mathematical genius seldom rivalled, contained his researches on the calculus of variation to the invention of which Euler was led by the study of the researches of Johann and Jakob Bernoulli…The study of isoperimetrical curves, the brachistochrone in a resisting medium and the theory of geodesics, previously treated by the elder Bernoullis and others, led to the creation of this new branch of mathematics, the Calculus of Variations. His method was essentially geometrical, which makes the solution of the simpler problems very clear.”–Cajori, A History of Mathematics, p. 234.
