To the Quartiers Latins in the Place des Martyrs at midday for the Brussels launch of my better half’s Le jour aux ignorants, published jointly with Brabant Wallon poet, Véronique Wautier. The discussion between the two ‘authors’ was very interesting. We are used to thinking that pictures illustrate text, but here it was the other way around; the pictures inspired the poems. And there was a great deal of (friendly) tension between competing visions that sometimes led them to leave out an image or a poem. On occasion, Véronique explained, she insisted on including a particular drawing although she had not yet drafted a poem to accompany it. The end result is a particularly coherent set of drawings and texts. Certainly the rich discussion provided a valuable insight into the dynamics of collaborative processes – and also to the aesthetic value of the resulting work.
