Rostam Carries the Sorcerer-King's Stone

From B5.10, Kavus Wars with Mazandaran. It illustrates B5.10.92–103 (to B5.10.106):

B5.10.92
At once by sorcery his body changed;A mass of mountain-stone before them ranged.
B5.10.93
Iran’s warriors stared; Rostam stood amazed,And at the sudden stone in wonder gazed.
B5.10.94
His spear-bearer lifted up the shaft,While Rostam stared in wonder at the craft.
B5.10.95
Then Kavus came with elephants in train,Tabiras, banners rolling through the plain.
B5.10.96
He asked, “Why linger here, O champion, still?What holds you from the battle and your will?”
B5.10.97
Said Rostam, “Fortune favored me in fight;The fire of victory rose before my sight.
B5.10.98
He saw my water-tempered spear draw near,Its tempered point before him bright and clear.
B5.10.99
I gave brave Rakhsh the rein and struck his waist;I thought to see him from his seat displaced.
B5.10.100
Instead he turned to stone before us all;Now bear him to the camp at Kavus’s call.”
B5.10.101
The strongest warriors strained with hand and knee;The stone stayed rooted where it seemed to be.
B5.10.102
Then Rostam laughed; he needed no such test;He spread his arms and pressed it to his chest.
B5.10.103
He raised the massive stone without a groan;The army marveled at his strength alone.
