L'algebre novvelle de Mr. Viete ...
L'algebre novvelle de Mr. Viete is a 1630 algebra treatise by François Viète, translated into French by Anthoine Vasset and printed in Paris by Pierre Rocolet. Its right triangle diagrams label sides with letters such as B, D and Z and with algebraic expressions like B quadrato plus D quadrato. The triangles are plain line drawings on a ruled page, so a designer might borrow their clean, schematic geometry and the way letters sit along edges.
