The Ars Magna by Ramon Llull Authors Umberto Eco Keywords: Ramon Llull (1232–1315/16), Tabula generalis, Christian, Jewish and Islamic cultures Abstract Beyond his general acceptance as a philosopher, theologician and religious man, Ramon Llull was also a scientist. In fact, he was a scientist in the way a scientist could be considered in the Middle Ages, with a society ruled by religion and by the absolute truth derived from the holy books (Bible, Koran and Torah). That truth, the “true Truth,” was different for each religion, and that fact was the origin of many disputes among believers of these three religions. Llull as a scientist emerges from his attempt to explain the religious fact not by the mere faith but by means of the reason. That purpose embebed all his work and converted him into one of the most important figures of science and humanities of the European Middle Ages.
