The main aim of this work is to present the most relevant news about the history of Lullism (the influence of Ramon Llull’s work and thoughts) in Portugal during the 14th and 15th centuries. Among other considerations on Lullian Portuguese studies (mainly the Livro da Corte Enperial and Boosco deleitoso), the textual links between D. Duarte’s Leal Conselheiro and the Introductorium magnae artis generalis -one of the apocryphal Lullian texts- are identified. At the same time, the identification of the so-called «reymonistas» (in D. Duarte’s book) with the members of the Congregation of Secular Cannons of Saint John Evangelist or lóios is explained.
