The author studies Ramon Llull and his wheels, old machines and Ars Magna. She describes his devices and how they are used in application, performance and interpretation. She also describes other algorithms used in digital humanities. The chapter also includes a discussion of the Ludic Algorithm. She anticipated using Llull’s studies to show how computing humanists or digital historians could possibly use his wheels to analyze and make sense of the hidden rules and assumptions that underline our own practice. However, she states that the best use for Llull’s machines might be to use the devices that are unfamiliar to aid in the problems of interpretation of mechanical and algometric systems that scholars deal with on a daily basis. The difficulty in an apparent and persuasive demonstration of the applicability of these systems to the interests of the academy is a major problem in the digital humanities. It is what keeps the field insular. The author concludes by stating that those involved in the practice of digital humanities can use Llull’s work to enhance their own studies.
