Abstract: In composition “The Vision of God” (1453), Nicholas of Cusa explores the question of the perception of beauty through “vision of the invisible”. In this discourse he leans on the earlier compendium of texts by Raymond Lully, particularly fragments from the text “From the Book of Discussion Between Peter and Raymond” (“Ex libro disputationis Petri et Raimundi”, late 1420’s). The article traces the understanding of the concept of beautiful by Nicholas of Cusa in evolution from the early compendium to the treatise “The Vision of God”. The key method of research lies in the rational reconstruction of the ideas of Cusa associated with the concept of beauty. The work also applies the methodology of comparative analysis of specificity of the use of certain notions characteristic for the ancient and scholastic philosophical traditions, but at this point, in the context of their implementation and re-interpretation particularly in the teaching of Nicholas de Cusa. Based on the conducted research, a conclusion is made that the definition of beauty common to the teaching of Nicholas de Cusa by no means is synonymous to Plato’s comprehension of the “beauty as such”. The concept of beauty in the teaching of Cusa does not suggest the establishment of any hierarchy of the beautiful, but rather alleviates all need for it. Analysis of compendium of the text of R. Lully along with the own compositions of Nicholas of Cusa shows how exhaustively and seamlessly do the ideas and cognitive constructs of R. Lully conform with the teaching of Nicholas of Cusa.
