Drawing and constructing polyhedra is a pastime that goes back to the Renaissance and perhaps even earlier times. Leonardo da Vinci (1452–1519), for one, created illustrations of various polyhedra for a 1509 book on the divine proportion by Luca Pacioli (1445–1517).
These immensely varied, crystal-like shapes, with regular features and flat faces (plane polygons), come in all sorts of configurations. Many people know of the five regular polyhedra: the tetrahedron, cube, octahedron, dodecahedron, and icosahedron. But the realm of polyhedra encompasses all sorts of additional forms: spiky stellated polyhedra, intricate, interlocked shapes, buckyballs and their cousins, and many more.
Fr. Magnus J. Wenninger, a mathematician and philosopher at Saint John’s Abbey in Collegeville, Minn., has been painstakingly and meticulously constructing polyhedra since 1961. His colorful, precise models, fashioned from paper, reflect the broad range of shapes that symmetrical polyhedra can take on.
Over the years, Father Magnus has written books and articles about how to construct accurate models of various types of polyhedra. Some of his many papercraft models, which are typically 30 to 40 centimeters in diameter, are now available for purchase from Saint John’s Abbey (see http://www.saintjohnsabbey.org/store/ and click on polyhedrons).
Creating such models is no simple task. Several years ago, I had a chance to observe Father Magnus quietly at work. His patience, care, and skill were clearly evident. And the results were awesome.
In recent years, Father Magnus has worked with other polyhedron experts to develop design software for creating polyhedral forms.
If you’re interested in templates and patterns for such forms, software such as Stella, developed by Robert Webb, provides a good starting point. For information about Stella, go to http://web.aanet.com.au/robertw/Stella.html.
