The De Divina Proportione is a three-volume work published 500 years ago – in 1509. Pacioli, a Franciscan friar,<br />
was known mostly as a mathematician, but he was also trained and keenly interested in art. De Divina Proportione<br />
explored the mathematics of the Golden<br />
Ratio. Containing illustrations of regular<br />
solids by Leonardo Da Vinci, Pacioli's<br />
longtime friend and collaborator, De Divina<br />
Proportione was a major influence on<br />
generations of artists and architects alike.<br />
Wh<strong>et</strong>her Leonardo proportioned his<br />
paintings according to the golden ratio has<br />
been the subject of intense debate. Salvador<br />
Dalí, on the other hand, explicitly used the<br />
Golden Ratio in his masterpiece, The<br />
Sacrament of the Last Supper. The<br />
dimensions of the canvas are a golden<br />
rectangle. A huge dodecahedron, with edges<br />
in Golden Ratio to one another, is<br />
suspended above and behind Jesus and<br />
dominates the composition.<br />
Dali’s “The Sacrament of the Last Supper” uses the Golden Ratio<br />
“The Golden Ratio has been used in many great works of art to achieve what we might term “visual<br />
effectiveness”. One of the properties contributing to such effectiveness is proportion – the size relationships<br />
of parts to one another and to the whole. The history of art shows that in the long search for an elusive<br />
canon of “perfect” proportion, on that would somehow automatically confer aesth<strong>et</strong>ically pleasing qualities<br />
on all works of art, the Golden Ratio has proven to be the most enduring”.<br />
-- Mario Livio<br />
De Divina Proportione discussed φ and its uses in architecture and art. Da Vinci studied Pacioli's text, and was<br />
fascinated by φ – it ended up taking a major role in many of this sk<strong>et</strong>ches and paintings. In particular, his infamous<br />
“Vitruvian Man” sk<strong>et</strong>ch is his illustration of how the human body supposedly embodies the divine proportion φ. Once<br />
Da Vinci embraced it, artists and architects all over Europe immediately jumped on the bandwagon, and it's pr<strong>et</strong>ty<br />
much continued to be used by artists and architects all the way to the present. The image in the right was used early<br />
on to promote the new ATSC 16:9 aspect ratio, borrowing from the images of both Da Vinci and Dali.<br />
