In ancient Egypt, the style of characters was always sacred, whether in flat or three-dimensional works, because when sculpting or depicting characters, the creator used standard geometric lattice to determine the rigor of the work. Byzantine art creation In practice, another unique measurement system is adopted, which is the "Byzantine concentric circle diagram method". Three concentric circles form a halo. This is a mathematical measurement system. A fixed two-legged compass is used. Assemble each character on the screen. This "structural" use makes the work flexible and vivid. In short, whether it is the use of geometric lattices or the Byzantine concentric circle diagram method, it has mathematical principles. The text is intended to explain:. ['Art creation is closely related to mathematics.', 'Art and mathematics have a long history.', 'Painting techniques have different characteristics in different times.', 'Advances in mathematics have promoted the development of painting techniques.']
