A young man lies spread-eagle in the center of a sand-covered arena, blood streaming from a gash above his eye. The guy who opened up this wound is straddled across his chest, pinning him down. All around them, more men are brawling in a terrifying tangle of fists and knees, shoulder charges and thrown elbows.

Lending a surreal edge to this scene is the combatants' attire. While some are bare-chested and others wear T-shirts, every one of them is clad in a pair of puffy-legged, brightly striped, 16th-century replica pantaloons.
