1938 Regarding Acephale. Letter from Georges Bataille to Patrick Waldberg:
'Half-measures and pretences become impossible, to the extent that they are stifling. We must have our face harsh, whether bare or masked, and no more back-and-forth uncertainty. In particular, I believe it is time that we must all – all! all those who can – go to the ends of mystical experience, something which is demanded by the experience of a man who does not lose himself. All the reservations that you may have cannot resist experience itself. At this point, there is no question that we will not do everything possible to burn like fire.'

1946 The elders of the secret society Acéphale meet with the aim of setting up the 'Encyclopædia Da Costa' review Da Costa Encyclopédique.

'Max Ernst, who found them too 'abstract', thoroughly understood that the constructions were only surrealist by chance. They are actually something quite different, ceremonial combat machines, 'traps to catch gods'. But 'surrealist' was the rare title that she would give them: (…) as in Masque à Lame ('Razor Mask'), Robert Lebel's poem that was illustrated with seven of her constructions, she borrows from the texts which she accompanies: Astonished, I watch you vitrify yourself; Your fingers of plaster; At Bercy when the time comes; Take care of sleep at the flanges; As mysterious as an essential transmutation; A cloth maybe; Beautiful aqueduct, still there!'
