It all started with an image we came across in a magazine.
It was of a man, bare chested, crouching on a mud floor. The hut was dimly lit with a single naked bulb, and a wood fire with a huge vat boiling on top of it flickered in the background. Next to the man lay a two foot long implement which looked like a scabbard. The man was staring away from the camera, seemingly at something in the distance with the right side of his face lit by the combined glow of the fire and the bulb. In his ear he had a centimetre-thick piece of wood and a cap adorned with animal horns. But it was his face that caught our attention. Darkened over time by tattoo ink, it was a canvas of circular designs around his eyes and grid-like markings on his cheeks.
