Notes and diagram on the topic of plane geometry, written in the Italian language [15--?]
A handwritten Italian manuscript of plane geometry notes, undated and probably from the 1500s, with a single construction diagram above a block of script. It was written as private study notes rather than for a printed audience. The page shows a circle with inscribed star polygons and tangent lines, which a designer could take as a source for radial, star-based layout grids and compass-built ornament.
