An attempt was made to reveal (owing to analysis of certain scientific and philosophic ideas and art practices of the 16— 17 th centuries) the relation between real and ideal dimensions in the aesthetic experience, inherent in this time interval. That was realized by means of outlining the aesthetic structure which appears from meditations about art and sensitivity of philosophers-rationalists on the one hand, and development of theatre and dance on the other hand: sources of the latter were accessible descriptions of performances, work of theorists and commentaries of art workers themselves. The found common character, field of imaginations about the way of subjects existence in the world were also aimed at demonstrating the then relation of art to life and thus, the way of art functioning, and thus, the method of thinking — if the supposition is brought forward that thinking does not often proceed from the rational bases but produces ideas, rationalizes itself in the process provoked by the fact that Jacques Ranciere called “aesthetically unrealized”.
