..I will endeavour to make clear to men of good will what the word 'material' means with regard to painting and that, without the material substance … - Giorgio de Chirico

..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.

I exhibited three paintings at the Salon d'Automne exhibition [Paris], which is the most interesting exhibition I have seen until now. Much more interesting than the Secession [in München]. My paintings [two words cancelled] were noticed and praised by the art critics. I think I will be very famous here in a few years time. Reading my name in the newspapers and seeing people notice my paintings and write about them has given me new and strange joy. – Paris is a beautiful city. Why do you remain in the monotony of Munich's heavy atmosphere? Here one can find everything one desires. Everything is refined and has spirit and everyday one learns something new. .The French are more intelligent than I thought. They laugh a lot, but they understand better than the Germans what is refined, strange and outside the ordinary.

Perfect knowledge of the space an object should occupy in a picture, and of the space that separates one object from another, establishes a new astronomy of things attached to our planet by the magic law of gravity. Canons of the Metaphysical aesthetic lie in the minutely-accurate and precisely-estimated use of surfaces and volumes.. ..We are building in paint a new Metaphysical psychology of things.
