references: Bibliotheca Mechanica [p. 227 : ""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."], DSB [IX, p. 430 : "his greatest work, which later became a mathematical classic"].
