Firstly for the design I decided that the two joined figures should be depicted upright [in Zadkine's first attempt the two brothers were sitting shoulder to shoulder].... two or three days later I was able to send him a photo of my new attempt, in which the two brothers are not only standing, but where the bond – the main idea is projected onto the statue in a hollow, in the heart of the composition the viewer can see a knot of hands, a symbol of the double inspiration.
