Propositions 9, 10 and 11 form a little group of proofs that command the reader: Bisect! Draw! Cut off! Construct! Proposition 9 and 10 show how to bisect an angle and a line, proposition 11 instructs on how to draw a line at right angles to another line and prove that you did. Since I really prefer circles to triangles or any other shape, all of these propositions reference earlier propositions that include circles. So, I can legitimately include circles in the artwork!
In the next three pieces of artwork, I’ll be returning fairly closely to the original color palette, established in the first few propositions. This piece uses just about every color that can be mixed from hansa yellow, sap green, quinacridone nickel azo gold, yellow ochre and white gesso. I tried to balance opaque and transparent in the painting of the piece – the underlying collage pieces of the Greek version of the proof and other drawings from the Elements are more or less visible depending on the opacity of the paint.
