The book of the architect, artist, art researcher Vyacheslav Loktev is the result of many years of studying and understanding the problems of art style on the material of Italian art of the XVI-XVII centuries. (architecture, painting, sculpture, music, scenography, poetry). An unconventional method of analysis that imitates the artist's compositional thinking and critical understanding of the experience of previous researchers of the Italian Baroque style leads the author to a fundamentally new interpretation of Baroque art in general and Michelangelo's work as an initiator of architectural and pictorial polyphonism in art. The book is designed for a professional and non-professional audience (historians and theorists, students of architectural and art universities, as well as art lovers).
