The Canon applies the basic mathematical concepts of Greek geometry, such as the ratio, proportion, and symmetria (Greek for "harmonious proportions") and turns it into a system capable of describing the human form through a series of continuous geometric progressions. Some scholars argue that Pythagorean thought influenced the Canon of Polykleitos. While none of Polykleitos's original works survive, Roman copies demonstrate his ideal of physical perfection and mathematical precision. The influence of the Canon of Polykleitos is immense in Classical Greek, Roman, and Renaissance sculpture, many sculptors following Polykleitos's prescription. The Canon itself has been lost but it is conjectured that Polykleitos used a sequence of proportions where each length is that of the diagonal of a square drawn on its predecessor, 1: √ 2 (about 1:1.4142). In the his Canon, a treatise he wrote designed to document the "perfect" body proportions of the male nude, Polykleitos gives us a mathematical approach towards sculpturing the human body. While his sculptures may not be as famous as those of Phidias, they are much admired. According to the philosopher and mathematician Xenocrates, Polykleitos is ranked as one of the most important sculptors of classical antiquity for his work on the Doryphorus and the statue of Hera in the Heraion of Argos. His works and statues consisted mainly of bronze and were of athletes. 450–420 BC) was a Greek sculptor from the school of Argos, and a contemporary of Phidias. A persistent view, based ultimately on the Pythagorean notion of harmony in music, holds that everything was arranged by Number, that God is the geometer of the world, and that therefore the world's geometry is sacred. Other relationships include the algorithmic analysis of artworks by X-ray fluorescence spectroscopy, the finding that traditional batiks from different regions of Java have distinct fractal dimensions, and stimuli to mathematics research, especially Filippo Brunelleschi's theory of perspective, which eventually led to Girard Desargues's projective geometry. Controversially, the artist David Hockney has argued that artists from the Renaissance onwards made use of the camera lucida to draw precise representations of scenes the architect Philip Steadman similarly argued that Vermeer used the camera obscura in his distinctively observed paintings. Computer art often makes use of fractals including the Mandelbrot set, and sometimes explores other mathematical objects such as cellular automata. Mathematical concepts such as recursion and logical paradox can be seen in paintings by René Magritte and in engravings by M. Magnus Wenninger creates colourful stellated polyhedra, originally as models for teaching. Mathematics has directly influenced art with conceptual tools such as linear perspective, the analysis of symmetry, and mathematical objects such as polyhedra and the Möbius strip. In Islamic art, symmetries are evident in forms as varied as Persian girih and Moroccan zellige tilework, Mughal jali pierced stone screens, and widespread muqarnas vaulting. Mathematics has inspired textile arts such as quilting, knitting, cross-stitch, crochet, embroidery, weaving, Turkish and other carpet-making, as well as kilim. Coxeter, while the De Stijl movement led by Theo van Doesburg and Piet Mondrian explicitly embraced geometrical forms. Escher made intensive use of tessellation and hyperbolic geometry, with the help of the mathematician H. The engraver Albrecht Dürer made many references to mathematics in his work Melencolia I. Another Italian painter, Piero della Francesca, developed Euclid's ideas on perspective in treatises such as De Prospectiva Pingendi, and in his paintings. In the Italian Renaissance, Luca Pacioli wrote the influential treatise De divina proportione (1509), illustrated with woodcuts by Leonardo da Vinci, on the use of the golden ratio in art. Persistent popular claims have been made for the use of the golden ratio in ancient art and architecture, without reliable evidence. Artists have used mathematics since the 4th century BC when the Greek sculptor Polykleitos wrote his Canon, prescribing proportions conjectured to have been based on the ratio 1: √ 2 for the ideal male nude. Mathematics and art have a long historical relationship. This article focuses, however, on mathematics in the visual arts. Mathematics can be discerned in arts such as music, dance, painting, architecture, sculpture, and textiles. Mathematics has itself been described as an art motivated by beauty. Mathematics and art are related in a variety of ways. Wireframe drawing of a vase as a solid of revolution by Paolo Uccello.
