of communication with his Imperial capital; while the intercourse of western Europe with Rome lay almost wholly at their mercy;[632] and far away at the opposite extremity of Aquitania the present count Humbert of Maurienne seems to have claimed, though he did not actually hold, one of the keys of another great mountain-barrier, in the Pyrenean county of Roussillon on the Spanish March.[633] [630] “Comes Maurianensis et Marchio Italiæ” is Count Humbert’s style in the marriage-contract of his daughter with John: _Gesta Hen._ (Stubbs), vol. i. p. 36. [631] All these places are named in the marriage-contract of John and Alice of Maurienne; _Gesta Hen._ (as above), pp. 36–40. [632] As says Rob. Torigni, a. 1171: “Nec aliquis potest adire Italiam, nisi per terram ipsius” [sc. comitis]. [633] _Gesta Hen._ (as above), p. 37. Humbert “concedit eis” [_i.e._ to John and Alice, in case he himself should have a son who must oust them from Maurienne] “in perpetuum et hæredibus eorum Russillun cum toto mandato suo sive pertinentiis suis omnibus,” as if he actually had it in his own hands. I have however failed to discover any connexion between Roussillon and Maurienne. In 1171[634] Henry’s diplomatic relations with the Alpine princes bore fruit in a proposal from Humbert of Maurienne for the marriage of his eldest daughter with the king’s youngest son. Humbert himself had no son, and by the terms of the marriage-contract his territories, Alpine and Pyrenean, were to be settled upon his daughter and her future husband,[635] in return for five thousand marks of English silver.[636] The contract was signed and ratified before Christmas 1172,[637] and soon afterwards Henry summoned his eldest son to join him in a journey into Auvergne for a personal meeting with Humbert. They reached Montferrand before Candlemas, and were there met not only by Humbert and his daughter but also by the count of Vienne,[638] the count of Toulouse and the king of Aragon.[639] How high the English king’s influence had now risen in these southern lands may be judged by the fact that not only King Alfonso of Aragon, a son of his old ally Raymond-Berengar, but also his former enemy Raymond of Toulouse, could agree to choose him as arbiter in a quarrel between themselves.[640] Raymond in truth saw in Henry’s alliances with Aragon and Maurienne a death-blow to his own hopes of maintaining the independence of Toulouse. Hemmed in alike to south and east by close allies of the English king whose own duchy of Aquitaine surrounded almost the whole of its north-western border, the house of St.-Gilles felt that it was no longer possible to resist his claim to overlordship over its territories. Henry carried his guests back with him to Limoges; there he settled the dispute between Raymond and Alfonso; and there Raymond
