Once the idea had taken root, I created maquettes (3D small scale sketches) to work out the idea in the round and explore the composition.
I have positioned Roger Casement facing land and as if he is stepping ashore. His torso opens to his left in the direction of his birthplace Sandycove and his head is turned to the right. If I have plotted this correctly, an imaginary line runs through his head from back to front between, respectively, London and Dublin.
