Der barycentrische Calcul, ein neues Hülfsmittel zur analytischen Behandlung der Geometrie [...].

8vo: [2]-xxiv-454-[1] pp.; 4 pl. (spotting throughout).

Contemp. half calf, marbled paper on covers, gilt-orn. spine with raised bands, marbled edges (corners and spine rubbed).

First edition of the most important work by the German mathematician and theoretical astronomer Mobius (1790-1868). Ill. with 4 engr. fold. pl. "The present volume represents not only Möbius' most important contribution, but the source of much of his later work. He had developed the fundamental ideas for his barycentric calculus in 1818 and by 1821 had decided that they warranted a book-length treatment. Since barycentric coordinates are a form of homogenous coordinate, Möbius is recognized by Feuerbach and Plücker as a discoverer of homogenous coordinates". (Bibl. Mechanica).
