The Geodesia is a Byzantine mathematical treatise intended as an appendix to a guide on siege warfare. Looking at the use of diagrammatic illustrations in the manuscript (BAV, Vat. gr. 1605), this article argues that the progression from two-dimensional drawings onto three-dimensional representations follows the “narrative arc” of the text from abstract mathematics to their application for siegecraft.
