Botticelli, like Da Vinci utilized the Golden Ratio in his paintings. For many, the Golden Ratio (also called Divine Proportion) which is a mathematical equation, is seen as a form of beauty. Da Vinci was also a mathematician. As photographers we would call this the rule of thirds.
Therefore, Botticelli’s The Birth of Venus represents beauty in two methods. It is also one of the most identifiable paintings in the world. And, on a side note, we get to see it here because of photography. (Smile.)
Mathematics, rightly viewed, possesses not only truth, but supreme beauty—a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show. Bertrand Russell
That’s right, there is beauty in mathematics. Or so I’ve read. But not being well versed in advanced math, I’ll take their word for it. It is my understanding that the Fibonacci sequence as well as the ability to recite Pi π beyond a certain length is also a form of beauty.
