The _Chanson de Roland_, the most ancient and characteristic of these poems, though extremely popular in the middle ages[19], passed with them into obscurity. The earliest allusion to the Oxford MS., which alone represents its earliest form, was made by Tyrwhitt a century ago. Conybeare forty years later dealt with it in the _Gentleman's Magazine_ of 1817, and by degrees the reviving interest of France in her older literature attracted French scholars to this most important monument of the oldest French. It was first published as a whole by M. F. Michel in 1837, and since that time it has been the subject of a very great amount of study. Its length is 4001 decasyllabic lines, and it concludes with an obscure assertion of authorship, publication or transcription by a certain Turoldus[20]. The date of the Oxford MS. is probably the middle of the twelfth century, but its text is attributed by the best authorities to the end of the eleventh. There are other MSS., but they are all either mutilated or of much later date. The argument of the poem is as follows:-- Charlemagne has warred seven years in Spain, but king Marsile of Saragossa still resists the Christian conqueror. Unable however to meet Charlemagne in the field, he sends an embassy with presents and a feigned submission, requesting that prince to return to France, whither he will follow him and do homage. Roland opposes the reception of these offers, Ganelon speaks in their favour, and so does Duke Naimes. Then the question is who shall go to Saragossa to settle the terms. Roland offers to go himself, but being rejected as too impetuous, suggests Ganelon--a suggestion which bitterly annoys that knight and by irritating him against Roland sows the seeds of his future treachery. Ganelon goes to Marsile, and at first bears himself truthfully and gallantly. The heathen king however undermines his faith, and a treacherous assault on the French rearguard when Charlemagne shall be too far off to succour it is resolved on and planned. Then the traitor returns to Charles with hostages and mighty gifts. The return to France begins; Roland is stationed to his great wrath in the fatal place, the rest of the army marches through the Pyrenees, and meanwhile Marsile gathers an enormous host to fall upon the isolated rearguard. There is a long catalogue of the felon and miscreant knights and princes that follow the Spanish king. The pagan host, travelling by cross paths of the mountains, soon reaches and surrounds Roland and the peers. Oliver entreats Roland to sound his horn that Charles may hear it and come to the rescue, but the eager and inflexible hero refuses. Archbishop Turpin blesses the doomed host, and bids them as the price of his absolution strike hard. The battle begins and all its incidents are told. The French kill thousands, but thousands more succeed. Peer after peer falls, and when at last Roland blows the horn it is too late.
