Albrecht Dürer was very important in Renaissance and the developements in it. His most important and influental aspect is that he introduced the scientific system of Italy to Northern Europe by using laws of proportions.
The Four Books on Human Proportions were highly influenced by Leonardo Da Vinci. The books investigate ideal human proportions. His studies show very technichal works of human anatomy and proportion. In the books, Dürer simplifies the complex structureof human body into sections using spheres, cylinders, cones, cubes and pyramids.
Dürer shows in the book that ‘Stereometry’, that is the science of measuring volume, can make drawing easier by solving the problem of foreshortening.
