In the sixth joust of the Twelve Combatants, Bijan, son of Giv, stepped into the arena against the fierce Turanian champion Ruyin, son of Piran. At first, both warriors strung their bows and circled one another from left and right, but their shafts could not pierce the heavy armor. Seeing arrows avail nothing, Bijan brandished his heavy Roman mace and closed in upon his foe. Gaining the upper hand in the heat of battle, Bijan struck a catastrophic blow upon Ruyin's helmet, breaking his skull so that blood and brain spilled forth. The young Turanian hero gave up his life upon his leopard-skin saddle, invoking the name of his father Piran, before tumbling headlong to the dust clad in iron.
Swiftly dismounting like a fierce warrior, Bijan cast his lasso and bound Ruyin's massive corpse onto the slain hero's steed as though it were a fallen elephant. Seizing Ruyin's purple silk banner adorned with a lion crest, Bijan took the horse's reins and rode triumphantly back to the designated summit where the Iranian chieftains waited. There, he offered prayers for the eternal glory and joy of the King and the commander-in-chief, mindful of the turning world wherein every steep ascent is followed by a sudden plunge.
