..the flat surface of a perfectly calm ocean [which] disturbs us.. ..by all the unknown that is hidden in the depth. - Giorgio de Chirico

Painting is the magic art, the fire set alight on the windows of the rich dwelling, as on those of the humble hovel, from the last rays of the setting sun, it is the long mark, the humid mark, the fluent and still mark that the dying wave etches on the hot sand, it is the darting of the immortal lizard on the rock burnt by the midday heat, it is the rainbow of conciliation, on sad May afternoons, after the storm has passed, down there, making a dark backdrop to the almond trees in flower, to the gardens with their washed colours, to the ploughmen's huts, smiling and tranquil, it is the livid cloud chased by the vehement blowing of Aeolus enraged, it is the nebulous disk of the fleeting moon behind the ripped-open funereal curtain of a disturbed sky in the deep of night, it is the blood of the bull stabbed in the arena, of the warrior fallen in the heat of battle, of Adonis' immaculate thigh wounded by the obstinate boar's curved tusk, it is the sail swollen with the winds of distant seas, it is the centuries-old tree browned in the autumn..

You misunderstood my words when I said that Michelangelo was a stupid artist.. .Because I have drunk from another source and a new and marvelous thirst burns my lips – how can I still believe in such artists?! I know what you are thinking when you ask me: 'isn't David a superman? This is how I used to feel, this is what I used to think. The majority of the world's great spirits thought it so.. ..but now a new air has entered my soul, a new song has reached my ears and the whole world appears totally changed – the autumn afternoon has arrived, the long shadows, the clear air, the serene sky –, in a word: Zarathustra has arrived, do you understand??.. ..It is only with Nietzsche that I can say I have begun a real life.

..can you [contemporary painters] ever get close, even vaguely, to the solidity, the transparency, the lyric strength of colour, to the clarity, the mystery, the emotion of any of the paintings of Fra Angelico, Piero della Francesca, Botticelli, Dürer, Holbein or of young Raphael? Friends, have you ever realized that with the oil colours used today this is absolutely impossible?. ..In the museums of Europe I have observed the work of the Flemish painters at length – those earlier, later as well as contemporary to the [brothers] Van Eycks – and I am convinced that the above mentioned brothers were not the discoverers of oil paint in its true sense, as is held today, but that what they did was introduce oil in emulsion with other substances, especially live and fossil resins, into so-called oil tempera emulsion, which was already known in the Flanders, to enable them through the use of veiling to give a greater finish, cleanliness and strength of colour to their painting.
'These oils which are their tempera' said Vasari, speaking of the Flemish [painters] in his Life of Antonello; and without doubt he was alluding to Flemish oil tempera emulsion, but it is sure, absolutely sure, that.. ..we are dealing with.. ..a tempera based mixture (egg, glue, resin, tempera etc) in which oil was only used as a means of unity and for the finish of the painting.
