This manuscript contains the text Tractatus Novus de Astronomia by Ramon Llull. Ramon Llull (c. 1232−1316) was an influential and prolific medieval writer, who was interested in many areas of knowledge and wisdom, including literature, philosophy, logic, astronomy, theology, and natural sciences. He wrote in Latin, Catalan, and Arabic, and is considered one of the first and most important writers in Catalan. He is honoured as a martyr by the Franciscan Order and was beatified by Pope Pius IX. The Tractatus Novus de Astronomia (New Treatise on Astronomy) was originally written in Latin in Paris in 1297 and later produced in Catalan under the title Tractat d’astronomia. It treats astronomy using the principles stablished in his Ars Magna. Inside the board is a volvelle or wheel chart, a series of movable dials that represent the orbits of the planets.
