After Pacioli, the golden ratio is more definitely discernible in artworks including Leonardo's Mona Lisa. [55] Another ratio, the only other morphic number, [56] was named the plastic number [c] in 1928 by the Dutch architect Hans van der Laan (originally named le nombre radiant in French). [57] Its value is the solution of the cubic equation
These ratios are used in depictions of the human figure and may become part of an artistic canon of body proportion within a culture. Academic art of the nineteenth century demanded close adherence to these reference metrics and some artists in the early twentieth century rejected those constraints and consciously mutated them.
Georges Seurat, 1887-88, Parade de cirque (Circus Sideshow) with a 4 : 6 ratio division and golden mean overlay, showing only a close approximation to the divine proportion. Matila Ghyka [30] and others [31] contend that Georges Seurat used golden ratio proportions in paintings like Parade de cirque, Le Pont de Courbevoie, and Bathers at ...
Illustration of the phalanges of a human hand. Despite the many advances made by modern scholars towards a clearer comprehension of the theoretical basis of the Canon of Polykleitos, the results of these studies show an absence of any general agreement upon the practical application of that canon in works of art.
Hierarchical proportion is a technique used in art, mostly in sculpture and painting, in which the artist uses unnatural proportion or scale to depict the relative importance of the figures in the artwork. For example, in Egyptian times, people of higher status would sometimes be drawn or sculpted larger than those of lower status.
In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities. Expressed algebraically, for quantities a {\displaystyle a} and b {\displaystyle b} with a > b > 0 {\displaystyle a>b>0} , a {\displaystyle a} is in a golden ratio to ...
Divina proportione (15th century Italian for Divine proportion), later also called De divina proportione (converting the Italian title into a Latin one) is a book on mathematics written by Luca Pacioli and illustrated by Leonardo da Vinci, completed by February 9th, 1498 [1] in Milan and first printed in 1509.

Much like a miniature Kleinfeld Bridal, Puccio’s crowded office is lined with racks of tulle and lace. Prior to this spring, Puccio says that she rarely had more than five to ten gowns available ...
