Fra Luca Bartolomeo de Pacioli was an Italian mathematician, Franciscan friar, collaborator with Leonardo da Vinci, and an early contributor to the field now known as accounting. He is referred to as the father of accounting and bookkeeping and he was the first person to publish a work on the double-entry system of book-keeping on the continent. He was also called Luca di Borgo after his birthplace, Borgo Sansepolcro, Tuscany.
In geometry, the rhombicuboctahedron, or small rhombicuboctahedron, is a polyhedron with eight triangular, six square, and twelve rectangular faces. There are 24 identical vertices, with one triangle, one square, and two rectangles meeting at each one. If all the rectangles are themselves square, it is an Archimedean solid. The polyhedron has octahedral symmetry, like the cube and octahedron. Its dual is called the deltoidal icositetrahedron or trapezoidal icositetrahedron, although its faces are not really true trapezoids.
Piero della Francesca was an Italian painter of the Early Renaissance. To contemporaries he was also known as a mathematician and geometer. Nowadays Piero della Francesca is chiefly appreciated for his art. His painting is characterized by its serene humanism, its use of geometric forms and perspective. His most famous work is the cycle of frescoes The History of the True Cross in the church of San Francesco in the Tuscan town of Arezzo.
Linear or point-projection perspective is one of two types of graphical projection perspective in the graphic arts; the other is parallel projection. Linear perspective is an approximate representation, generally on a flat surface, of an image as it is seen by the eye. Perspective drawing is useful for representing a three-dimensional scene in a two-dimensional medium, like paper.
The Vitruvian Man is a drawing by the Italian Renaissance artist and scientist Leonardo da Vinci, dated to c. 1490. Inspired by the writings by the ancient Roman architect Vitruvius, the drawing depicts a nude man in two superimposed positions with his arms and legs apart and inscribed in both a circle and square. Described by the art historian Carmen C. Bambach as "justly ranked among the all-time iconic images of Western civilization," the work is a unique synthesis of artistic and scientific ideals and often considered an archetypal representation of the High Renaissance.
The cultural and artistic events of Italy during the period 1400 to 1499 are collectively referred to as the Quattrocento from the Italian word for the number 400, in turn from millequattrocento, which is Italian for the year 1400. The Quattrocento encompasses the artistic styles of the late Middle Ages, the early Renaissance, and the start of the High Renaissance, generally asserted to begin between 1495 and 1500.

Jacopo de' Barbari, sometimes known or referred to as de'Barbari, de Barberi, de Barbari, Barbaro, Barberino, Barbarigo or Barberigo, was an Italian painter, printmaker and miniaturist with a highly individual style. He moved from Venice to Germany in 1500, thus becoming the first Italian Renaissance artist of stature to work in Northern Europe. His few surviving paintings include the first known example of trompe-l'œil since antiquity. His twenty-nine engravings and three very large woodcuts were also highly influential.
The decade of the 1490s in art involved some significant events.

Divina proportione, later also called De divina proportione is a book on mathematics written by Luca Pacioli and illustrated by Leonardo da Vinci, completed by February 9th, 1498 in Milan and first printed in 1509. Its subject was mathematical proportions and their applications to geometry, to visual art through perspective, and to architecture. The clarity of the written material and Leonardo's excellent diagrams helped the book to achieve an impact beyond mathematical circles, popularizing contemporary geometric concepts and images.
Mathematics and art are related in a variety of ways. 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.

who riding then from hand to hand,
with the banner in the wind of the snake,
honor and glory of Lombardy,
with many great gentlemen in company.
