![]() “ scientific representation of receding figures in space …” Kenneth Clark writes: “ If man was the measure of all things, physically perfect man was surely the measure of all beauty, and his proportion must in some way be reducible to mathematical terms and correspond to those abstract perfections, the square, the circle, and the golden section.” Clark goes on to remind us that “ This union of art and mathematics is far from our own way of thinking, but it was fundamental to the Renaissance. Peter’s Basilica, is Euclid and perfectly centered in the work is Plato, as represented by Leonardo. ![]() Raphael himself is Apelles, the great painter Bramante, the architect of St. This incorporates many of the mathematical theories of Luca and Leonardo in addition, most of the historically famous characters from ancient Greece are represented. ![]() Just after the publication of De Divina Proportione, Raphael painted his massive and extraordinary fresco, ‘ The School of Athens’, in the Vatican. The two versions of Mona Lisa are suffused with mathematical similarities as well as the divine proportion. Leonardo sees in geometry the precision through which he can construct unique compositions in perfect harmony within its setting. Rather it is geometry that interests him most and that is most relevant to his art. While Leonardo himself writes in general terms of the importance of mathematics, it is unlikely that this refers to the disciplines of algebra, trigonometry and calculus, common in today’s classrooms. When Leonardo returned to Florence in 1500 he did so in the company of his mathematics tutor, Fra’ Luca Pacioli, and from an educational point of view this relationship cannot be underestimated. When Fra’ Pietro da Novellara and others write to Isabella d’Este in the early years of the 16th Century, there is significant reference that Leonardo has no patience to paint because of his constant studies of geometry. At the same time, one can sense Leonardo disguising his own new-found knowledge in painting techniques that manifest themselves in his later works. The message is not lost on Leonardo, who loses little time in diverting his loyalties to the French. In the meantime, when the French finally re-occupy Milan in 1500, they take from Leonardo’s circle the Ferrarese architect, Giacomo Andrea, who had interpreted and translated some of Vitruvius’ work for Leonardo, and subsequently have him publicly beheaded and quartered on May 12, silencing a vital voice of science and independent thought. Fra’ Luca expounds the theory in 1498, while teaching in Milan, and later, in 1509, he and Leonardo collaborate to publish De Divina Proportione, in which is seen one of the most famous drawings associated with Leonardo: ‘ Proportion Man’, also known as ‘ Vitruvian Man’, which has become one of the world’s most iconic images. Why is this important? To Leonardo, and other Renaissance masters, the ‘Golden Ratio’ became a critical instrument in the matter of accurate proportionality. Thus this our proportion is the formal being of (according to Timaeus) heaven, attributing to it the figure of the solid called Dodecahedron, otherwise known as the solid of twelve pentagons.” Luca Pacioli, De Divina Proportione “ As God confers being to the celestial virtue, called by the other name ‘fifth essence’, and through that one to the other four simple bodies, that is, to the four earthly elements … and so through these to every other thing in nature. The letter ‘A’, illustration and design, for the De Divina Proportione by Luca Pacioli. In the fifth attribute of God, functional comparison, Pacioli sets the ‘Divine Proportion’ in relation to the Platonic quintessence. ![]() The formula was first recorded by Euclid, c. It is referred to as the ‘Golden Section’: also known as the ‘Golden Rule’, ‘Golden Cut’, ‘Golden Number’, ’Golden Proportion’, ‘Golden Ratio’. There exists in mathematics a unique number, 0.618, which is the only one when divided into unity (1.0) yields its own reciprocal – 1.618. “ Non mi legga chi non e matematico.” “ Let no one read me who is not a mathematician.”Ĭertainly the instruction of Luca Pacioli in Milan was revealing to Leonardo, and this was manifested particularly in the ‘ Last Supper’. At times, he seems obsessed with these issues: while working on Mona Lisa for example, Leonardo is reported by Fra’ da Novellara to be concentrating intensely on geometry. The important relationship of mathematics to art cannot be understated when discussing Leonardo’s later work, and in numerous documents, letters and notes, the relevance of this is well documented.
