Linear perspective was just being introduced into the artistic world.

Mathematical references include a compass for geometry, a magic square and a truncated rhombohedron, while measurement is indicated by the scales and hourglass.

Mathematics has itself been described as an art motivated by beauty.

Mathematics can be discerned in arts such as music, dance, painting, architecture, sculpture, and textiles.

This article focuses, however, on mathematics in the visual arts.

Persistent popular claims have been made for the use of the golden ratio in ancient art and architecture, without reliable evidence.

The engraver Albrecht Drer made many references to mathematics in his work Melencolia I.

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.

Magnus Wenninger creates colourful stellated polyhedra, originally as models for teaching.

Mathematical concepts such as recursion and logical paradox can be seen in paintings by Ren Magritte and in engravings by M.

C. Escher. Computer art often makes use of fractals including the Mandelbrot set, and sometimes explores other mathematical objects such as cellular automata.

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.

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 worlds geometry is sacred.

His works and statues consisted mainly of bronze and were of athletes.

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.

While his sculptures may not be as famous as those of Phidias, they are much admired.

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 none of Polykleitoss original works survive, Roman copies demonstrate his ideal of physical perfection and mathematical precision.

Some scholars argue that Pythagorean thought influenced the Canon of Polykleitos.

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.

In the Middle Ages, some artists used reverse perspective for special emphasis.

The Muslim mathematician Alhazen (Ibn al-Haytham) described a theory of optics in his Book of Optics in 1021, but never applied it to art.

The Renaissance saw a rebirth of Classical Greek and Roman culture and ideas, among them the study of mathematics to understand nature and the arts.

Two major motives drove artists in the late Middle Ages and the Renaissance towards mathematics.

First, painters needed to figure out how to depict three-dimensional scenes on a two-dimensional canvas.

Second, philosophers and artists alike were convinced that mathematics was the true essence of the physical world and that the entire universe, including the arts, could be explained in geometric terms.

In 1415, the Italian architect Filippo Brunelleschi and his friend Leon Battista Alberti demonstrated the geometrical method of applying perspective in Florence, using similar triangles as formulated by Euclid, to find the apparent height of distant objects.

Brunelleschis own perspective paintings are lost, but Masaccio s painting of the Holy Trinity shows his principles at work.

Piero studied classical mathematics and the works of Archimedes.

He was taught commercial arithmetic in abacus schools; his writings are formatted like abacus school textbooks, 20 perhaps including Leonardo Pisano ( Fibonacci )s 1202 Liber Abaci.
