Geometry and Logic. The Shape of Mathematical Proof from Antiquity to the Early Modern Age

The diagrams of Euclid's Elements. Plane geometry, arithmetic, irrational magnitudes and solid geometry

speaker: Ken Saito (Osaka Prefecture University)

abstract: Each proposition of Euclid's \textit{Elements} is accompanied by a diagram in mediaeval manuscripts which practically constitute exclusive source of our knowledge of this work. I have already discussed some features of the diagrams mainly in plane geometry, and showed how the diagrams in today's editions are different from those the manuscripts provide. In this communication I sum up my researches and give an overview of the manuscript diagrams of the \textit{Elements}, including those in arithmetical books (Books VII-IX), and in the theory of inexpressible (irrational) magnitudes (Book X).
