How are traditional Chinese gardens structured? Why is everything in them subordinated to the idea of tranquility and contemplation? This lecture will introduce the philosophy of Chinese garden art, its techniques, and aesthetics. It will discuss reliefs, water bodies, plants, and architectural details that inspire landscape design even today. Traditional Chinese gardens are not just decorations of the landscape, but a way of perceiving the world and creating an ideal space for reflection and contemplation. Each detail-from hills and ponds to the curves of paths-carries meaning, giving rise to a complex system of symbols, lines, and perspectives. The creators of such gardens aimed to recreate a whole universe in miniature-with mountains, water bodies, houses, trees, and places for solitude. The lecture at the Lermontov Library will reveal to listeners the principles of forming a Chinese garden, discuss their spatial logic, perception in motion and stillness, methods of creating relief, use of water, building layout, and selection of plants. All these elements work in harmony and are aimed at creating a multilayered and profound composition capable of influencing human perception. Special attention will be given to the book "On Chinese Gardens" by Chen Congzhou, recognized as a classic of the genre and published for the first time in Russian with a reproduction of the original Chinese manuscript. Its brief presentation during the meeting will allow a glimpse into the eastern tradition through the eyes of an outstanding researcher. The lecture will be conducted by Olga Ushakova-a lecturer at the Department of Architecture of SPbGASU, a member of the Union of Architects and the Union of Artists of Russia. Her talk will combine a scientific approach with an artistic perspective on the ancient garden art of China. This event will be interesting for anyone interested in landscape architecture, eastern philosophy, art history, and cultural traditions of other countries.
