WebGreek geometry with insightful commentary. David Hilbert observed that Pappus's Theorem is equivalent to the claim that the multiplication of lengths is commutative (see, e.g., Coxeter [ 3, p. 152]). Thomas Heath believed that Pappus's intention was to revive the geometry of the Hellenic period [ 11 , p. 355], but it wasn't until 1639 WebPappus goes to some length in his study of the three claasic means of anticuity, the arithmetic, the geometric, and the har-monic. Recall the chapter on Pythagoras a : c = a¡b : b¡c Harmonic a : a = a¡b : b¡c Arithmetic a : b¡a¡b : b¡c Geometric where b is the designated mean of a and c. He o®ers geometric solutions of each.
