The Song of Roland: Legend Born from a Mountain Ambush

In the high passes of the Pyrenees, sometime in the summer of 778, a portion of Charlemagne's army was ambushed and destroyed. Centuries later, this obscure defeat was transformed into one of the towering works of medieval European literature: the Song of Roland, an Old French chanson de geste of roughly 4,000 lines, composed sometime between 1040 and 1115, with most alterations settled by around 1098.

The poem survives today primarily through a single manuscript, held at the Bodleian Library at the University of Oxford, written in Anglo-Norman and dated between 1129 and 1165. Eight additional manuscripts and three fragments touching on the Roland material also exist, testifying to the story's enduring grip on medieval and Renaissance audiences alike. Scholars have long debated who composed it; the manuscript itself names a poet, Turold — Turoldus — though little else is known of him.

The dating of the poem hinges partly on a small phrase: d'oltre mer, 'from overseas,' used three times to describe Muslims who came to fight in Spain and France. Because this term became common usage during and after the First Crusade of 1096–1099, some scholars argue the poem — or at least parts of it — was composed or revised after the Crusade. Others believe the term was used more generically before that, pointing instead to the Castilian campaigns of the 1030s as an early inspiration, and suggesting the poem was already established enough to influence crusading ideology.

The story it tells departs sharply from history. According to Einhard's Vita Karoli Magni, written in the late eighth century, the attackers at Roncesvalles were actually Basques taking revenge for the sack of Pamplona. But the poem recasts the battle as a clash between Christendom and Islam. In its account, Charlemagne's army has campaigned in Spain for seven years, and only Zaragoza — held by King Marsile, a follower of 'Mahumet and Apollin' — remains unconquered.

Threatened by Charlemagne's power, Marsile takes the counsel of his advisor Blancandrin and offers surrender, treasure, and conversion to Christianity if the Franks will withdraw. Charlemagne's men, weary after years of war, accept. A messenger must be chosen to carry the terms to Marsile's court — and Roland, Charlemagne's nephew and the poem's hero, nominates his own stepfather, Ganelon, for the task.
