Giv's Charger Will Not Move

From C3.25, Giv’s Horse Falters before Piran. It illustrates C3.25.6–16:

C3.25.6
Giv saw him there, and wheeled, and spurred to breachThe ring of guards that kept Piran from reach.
C3.25.7
He speared four men and hurled them to the ground,From those before Piran, his guards around.
C3.25.8
Piran, son of Viseh, strung his bow,And rained sharp arrows fiercely on his foe.
C3.25.9
Bold Giv held up his shield above his head,And charged with spear, a wolf where blood was shed.
C3.25.10
But when he sought to close with fierce Piran,And thrust his spear against the chief of Turan,
C3.25.11
His charger halted, rooted to the ground;It would not move from where it now was found.
C3.25.12
Enraged, he lashed his swift steed with the whip,And anger loosed the words upon his lip.
C3.25.13
He seethed, then let his bitter curses flyAgainst the evil Div beneath the sky.
C3.25.14
Then with his wolf-skin shield above his head,He dropped his spear and took his bow instead.
C3.25.15
He drew and loosed to pin Piran’s strong handAgainst the shield he raised to make his stand.
C3.25.16
Four shafts he shot against Piran’s proud crown;They failed to harm that chief of dread renown.
