The main aim of the paper is to find a non-mimetic understanding of art in proper Plato’s thought which is known exactly for his formulation of the concept of “mime-sis” in the dialogue Republic. The author of the contribution presumes to find the non-mimetic understanding also in the dialogue Ion, in which the creation of art is presented as madness from inspiration. Plato’s Ion can be understood with the aid of Levinas’s notion of alterity, as well as of how it disturbs knowledge. This broad scheme does not exhaust the possibilities of similarities between both of the philosophers, and it opens the way to clarify singularities: Plato’s notion of magnetism, the rest of Divini-ty in art-work, the Levinasian concept of trace, or the concept of ambiguity.
