According to varying accounts, he either sank it deep into a poisoned stream, where it is still supposed to lie, or, striking it against the mighty rocks, cleft them in two, without even dinting its bright blade.
"And Roland thought: 'I surely die; but, ere I end, Let me be sure that thou art ended too, my friend! For should a heathen hand grasp thee when I am clay, My ghost would grieve full sore until the judgment day!' Then to the marble steps, under the tall, bare trees, Trailing the mighty sword, he crawl'd on hands and knees, And on the slimy stone he struck the blade with might-- The bright hilt, sounding, shook, the blade flash'd sparks of light; Wildly again he struck, and his sick head went round, Again there sparkled fire, again rang hollow sound; Ten times he struck, and threw strange echoes down the glade, Yet still unbroken, sparkling fire, glitter'd the peerless blade." BUCHANAN, _Death of Roland_.
Finally, despairing of disposing of it in any other way, the hero, strong in death, broke Durandana in his powerful hands and threw the shards away.
Horse and sword were now disposed of, and the dying hero, summoning his last strength, again put his marvelous horn Olivant to his lips, and blew such a resounding blast that the sound was heard far and near.

The effort, however, was such that his temples burst, as he again sank fainting to the ground.
One version of the story (Turpin's) relates that the blast brought, not Charlemagne, but the sole surviving knight, Theodoricus, who, as Roland had been shriven before the battle, merely heard his last prayer and reverently closed his eyes.

Then Turpin, while celebrating mass before Charlemagne, was suddenly favored by a vision, in which he beheld a shrieking crew of demons bearing Marsiglio's soul to hell, while an angelic host conveyed Roland's to heaven.
Turpin immediately imparted these revelations to Charlemagne, who, knowing now that his fears were not without foundation, hastened back to Roncesvalles.

Here the scriptural miracle was repeated, for the sun stayed its course until the emperor had routed the Saracens and found the body of his nephew.

He pronounced a learned funeral discourse or lament over the hero's remains, which were then embalmed and conveyed to Blaive for interment.
Another version relates that Bishop Turpin himself remained with Roland in the rear, and, after hearing a general confession and granting full absolution to all the heroes, fought beside them to the end.
