This paper presents some of the most important and previously unpublished writings by Peirce on Euler diagrams including variants written on a sphere (Ms 479), their novel extensions for negative terms (Ms 481, 1896-7, Ms 1147, 1901), and existentials and shading (Ms 855), among others. We restore Peirce's original drawings explain the main innovations. As Euler diagrams were not designed to reason about relative terms, Peirce's interest was not in their mathematical application or problem solving but in showing what the basic elements of syllogistic reasoning are.
