Mikhail SilianDissertation project

Does our ability to see shapes, or to observe locomotion, depend on our perception of colors? And in what sense does the perception of colors provide the basis for scientific knowledge? In my dissertation project, I reconstruct how Claudius Ptolemy, an Alexandrian polymath who lived in the second century C.E., answered these questions. I focus on Ptolemy’s Optics, the treatise originally written in Greek but only extant in the XIIth century Latin translation. In the second book of the Optics, Ptolemy explains how we perceive such properties of visual objects as figure, size, shape, or opacity. In contrast, in the following books Ptolemy focuses on studying optical images by creating their geometrical models. In this context, it does not seem clear, how Ptolemy’s account of visual properties from the second book prepares the reader for the geometrical exposition of optical laws in the following books. In my project, I will clarify this issue, as well as present my reading of Ptolemy’s more general theory of visual perception.
