“There is not a canvas of that time that does not foreshadow the overthrow of the foundations on which the human race thought itself firmly established, where it felt itself secure. At the moment when the Ballets Russes were at their height, when the Neo-Impressionists and Fauves had dispensed with the drawing style of the Renaissance because it could not contain the purity of the colour - these humbly painted, angular, grey, ascetic pictures were, really, an unwelcome sight. It was not any upheaval of a geological nature that they prefigured, but a cataclysm in the human order. No tremor of the earth was registered, but a tremor of the spirit that disturbed the intellect of civilised man, too long the slave of his immobilised senses. At last he was beginning to suspect that something dangerous was approaching.”
