This task is sometimes supplemented by a more creative and challenging assignment, that is, the design and construction of a perspective box.

### Architecture and Mathematics

A perspective box is an empty box with, on the inner sides, perspective pictures giving a surprising spatial effect when observed through the peephole. The students who take up the challenge are in the first place inspired by the six still existing antique wooden perspective boxes, especially because they were created by Dutch seventeenth-century painters of architecture and interiors. In this article the setup of the perspective in these boxes will be discussed. But for a clear comprehension, we begin by reviewing the principles of linear perspective and their implications for the way perspective images can best be viewed.

In , Jesuit priest and architect Juan Bautista Villalpando published In Ezechielem Explanationes , a massive three-volume scriptural exegesis on the Book of Ezekiel. Initially the latter appears out of place in a Scriptural exegesis but he explained that the purpose of this book was to provide a guide for theologians so that they can form a mental idea or image of Temple, for their understanding and enlightenment of the entire Temple.

However, throughout the text he points to the utility of the book to architects. For Villalpando the laws of optics were essential to the norms of perspective. Moreover, the sense and structure of seeing was a crucial element to the norms of mathematic and architecture, it is also a central theme in his theology.

This paper examines his theory and his proposal of perspective for architecture drawing. Quattrocento perspective and Spanish sixteenth-century stereotomy share a number of concepts, problems and methods, although there seems to be no direct substantial connection between them. This suggests the existence of a common source, but it is not easy to identify it. Escher , who is perhaps the most astonishing recent example of an artist whose work contains a multitude of connections between mathematics and art.

Yet he did not reject mathematics, but instead figured out in his own way, using various mostly pictorial sources, the mathematics that he needed in order to realize his ideas and visions.

Escher celebrated mathematical forms: polyhedra as decoration, stars, or living structures, mvbius bands, knots, and spatial grids. He used and sometimes fused various geometries in his work -- Euclidean in his tessellations, hyperbolic in his Circle Limit series, projective in depicting scenes in linear perspective, spherical in prints and his carved spheres.

He employed topological distortions and transformations, strange or multiple perspectives, and visual recursion. He explored the topic of symmetry and tessellation in the plane, on the sphere, and in the Poincari disk, developing his own "layman's theory" of classification of types of planar periodic tilings and symmetric coloring of them, anticipating mathematician's and crystallographer's later studies of these topics. And though Escher's work gained him the admiration of mathematicians and scientists, he felt isolated as an artist. Today there are many artists whose work is directly or indirectly inspired by Escher's work.

While he has left us his own legacy, others are continuing to explore some of the paths he blazed and also are striking out on new paths from these. Ivars Peterson [R13] showcases a wide selection of art and artists of today exemplifying the strong symbiosis between art and mathematics.

Two others, [R2] and [R18], contain thoughtful commentaries and discussions as well as essays and art by contemporary artists. Several books and web sites provide text, ideas, problems and projects for courses focused on art and mathematics. Many of these are listed on the Mathematics Awareness Month web site, which also contains essays by Mark Frantz and Paul Calter, who teach courses on mathematics, art, and architecture.

There are several organizations that are dedicated to fostering interaction between art, mathematics, and science. Most hold annual conferences at which artists and mathematicians and many others gather to exhibit, lecture, discuss, and mingle; often proceedings print or electronic publish the presentations. Web sites for several of these are listed under Organizations below. Intelligencer , v.
