"Photography is not an art. Neither is painting, nor sculpture, literature or music. They are only different media for the individual to express his aesthetic feelings… You do not have to be a painter or a sculptor to be an artist. You may be a shoemaker. You may be creative as such. And, if so, you are a greater artist than the majority of the painters whose work is shown in the art galleries of today."
-Alfred Stieglitz

 The Sabbath of Witches (Le Sabbat des Sorcières) by Francisco Goya, from 1797-1798,  Lazaro Galdiano Museum, Madrid. 
This is one of eight paintings commissioned by the Duchess of Osuna for her country house at Alameda. The subject, similar to that of etching No. 60 of Los Caprichos, enabled Goya to combine his flair for fantasy with savage attacks on the Church’s abuses and exploitation of superstitions and fears, which were deeply rooted in the popular imagination.

Carnation, Lily, Lily, Rose by John Singer Sargent, 1885-1886. 
Conceived under the most unusual of circumstances, and nurtured in a remarkable setting at Broadway, this painting is overwhelmingly held out by the public — then as well as today — to be the most favored painting of all his work. It is universally believed to be one of his masterpieces. Carnation, Lily, Lily, Rose, the title lifted from the light-hearted lyrics of a popular song, is a triumph of John’s use of light which would never be equaled in quite the same way.
