A version of the Mona Lisa known as the Isleworth Mona Lisa was first bought by an English nobleman in 1778 and was rediscovered in 1913 by Hugh Blaker, an art connoisseur.

A bijection with the sums to n is to replace 1 with 0 and 2 with 11. The number of binary strings of length n without an even number of consecutive 0 s or 1 s is 2F n. For example, out of the 16 binary strings of length 4, there are 2F 4 = 6 without an even number of consecutive 0 s or 1 s—they are 0001, 0111, 0101, 1000, 1010, 1110. There is ...

Using X-rays to peer into the chemical structure of a tiny speck of the celebrated work of art, scientists have gained new insight into the techniques that Leonardo da Vinci used to paint his ...
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.

Dianne Hales quotes the sixteenth-century painter and art theorist Gian Paolo Lomazzo as identifying two versions of the painting: "In 1584, in his Treatise on Painting, the Florentine artist and chronicler Giovanni Paolo Lomazzo, a supposed acquaintance of Leonardo's longtime secretary Melzi, wrote that 'the two most beautiful and important portraits by Leonardo are the Mona Lisa and the ...
