That these educational efforts were not wholly vain, there is some reason to believe. Robert has not, like his youngest brother, Henry, received the flattering title of Beauclerc, and there is no direct evidence that he knew Latin. Yet some notable accomplishments he did have. Not to mention his affable manners, he was famed for his fluency of speech, or ‘eloquence’, especially in his native tongue.[16] And if towards the close of his unfortunate life he became the author, as has been supposed, of an extant poem in the Welsh language,[17] it may perhaps be allowed that in his youth he had acquired at least a taste and capacity for things literary.[18] The hopes of William and Matilda were early centred upon their oldest son, and his initiation into the politics of his ambitious father was not long delayed. As the result of a revolution at Le Mans, the youthful Count Herbert II with his mother and his sister Margaret had been driven into exile, and the direct rule of Geoffrey Martel, count of Anjou, had been established in Maine.[19] William of Normandy, ever jealous of Angevin expansion, was not slow to realize what his policy should be in the light of these events. By giving support to the exiles he might hope to curb the ambition of Geoffrey Martel and to extend Norman influence, conceivably Norman domination, over Maine. Accordingly, at an undetermined date between 1055 and 1060—probably between 1058 and 1060[20]—he entered into a treaty of far-reaching significance with the exiled count. Herbert formally became Duke William’s vassal for the county of Maine, and agreed that, if he should die childless, the duke should succeed him in all his rights and possessions. And further, a double marriage alliance was arranged, according to which William promised the count one of his infant daughters, and Robert Curthose was affianced to Herbert’s sister, Margaret of Maine.[21] Thus Robert, while still a mere child, was made a pawn in the ambitious game which his father was playing for the possession of a coveted county. Margaret, too, was young; but the duke brought her to Normandy, and, placing her in the ward of Stigand de Mézidon, made due provision for her honorable rearing until the children should arrive at an age suitable for marriage.[22]
