Prior to the 1400s, the designs were highly proprietary and undocumented to avoid competition. You are going to have a problem going further back than the “Sancy design”. If some of the Jewish gem cutters created notebooks that were passed down and now published, you might go back into Spain a bit older. Does anyone know of these types or records?
