Final answer:
Polykleitos's canon of perfect proportions based on mathematical ratios became the new measure of perfect proportions after the Kritios Boy.
Step-by-step explanation:
Polykleitos, an ancient Greek artist and art theorist, developed a canon for the creation of the perfect male body based on mathematical proportions. His work, such as the statue of Doryphoros, emphasized a balanced, harmonious representation of the human form. This canon became the new measure of perfect proportions after the Kritios Boy.
Polykleitos believed that beauty consisted in the proportions of different body parts, such as the fingers, palm, forearm, and upper arm, in relation to each other. This mathematical approach to art allowed artists to create sculptures that were both lifelike and aesthetically pleasing.
By using precise mathematical calculations, Polykleitos and other Greek artists adjusted for the imperfections of human perception to create the illusion of perfection in their sculptures. Their attention to detail and mastery of proportions contributed to the development of the Severe style, which emphasized naturalism and movement.
