Research on Human Body Proportion, written by Deutsches Delle, 4 volumes in total. Published in 1528. This book discusses painting and the proportion of the human body, trying to find the most beautiful line shape and the most beautiful proportion, and express them through mathematical formulas. It emphasizes that "through mathematical means, we can find out the existing beauty, so as to be closer to the goal of perfection". I believe that the form of beauty is universal and eternal, and I also see the variability and relativity of beauty. I believe that we must find the law of beauty from different body proportions. It has great influence on the perspective and human anatomy. [1]
