The king having died, Ogier next married the widowed queen, and would thus have become King of France had not Morgana the fay, jealous of his affections, spirited him away in the midst of the marriage ceremony and borne him off to the Isle of Avalon, whence he, like Arthur, will return only when his country needs him.
[Sidenote: Roland and Oliver.] Another _chanson de geste_, a sort of continuation of "Ogier le Danois," is called "Meurvin," and purports to give a faithful account of the adventures of a son of Ogier and Morgana, an ancestor of Godfrey of Bouillon, King of Jerusalem.

In "Guerin de Montglave," we find that Charlemagne, having quarreled with the Duke of Genoa, proposed that each should send a champion to fight in his name.
Charlemagne selected Roland, while the Duke of Genoa chose Oliver as his defender.

The battle, if we are to believe some versions of the legend, took place on an island in the Rhone, and Durandana, Roland's sword, struck many a spark from Altecler (Hautecler), the blade of Oliver.

The two champions were so well matched, and the blows were dealt with such equal strength and courage, that "giving a Roland for an Oliver" has become a proverbial expression.
