We found it necessary, both from common consideration for the patache-horse, and our own necks, to walk up the two miles of steep ascent, which occur after passing this last castle. On the top of the hill all vegetation appears to cease, excepting a few shrubby dwarf firs, and a profusion of aromatic plants, such as juniper, lavender, southernwood, and wild thyme, which delight in the stony hot-bed afforded by the interstices of disjointed rocks. The view from the high table of ground to which we climbed at length fully repaid our exertions, and may be almost compared, for extent and beauty, to those from the church of Fourvieres, and the Montagne de Rochepot. Towards the north we surveyed not only the valleys of Montelimart and the Drome, but nearly the whole of the route of the three preceding days, bordered on the one side by the abrupt and lofty mountains, from which the latter river takes its source, and on the other by the steep banks of the Rhone. On proceeding a little farther, over a road which consisted of the native rock in all its native inequality, we caught sight of the Comtat Grignan, and the great plain of Avignon, into which that district opens in a south-western direction, flanked on the east by a colossal Alp, called Mont Ventou, on whose long ridge traces of snow were still visible. In the centre of the Comtat, [16]Chateau Grignan is easily distinguished by the grandeur of its outline and proportions, and the tall insulated rock on which it stands, somewhat resembling that on which Windsor Castle is situated, though inferior in size. Its effect is somewhat heightened by several other smaller crags at different distances, which thrust themselves through the scanty stratum of soil, each crowned with a solitary tower, or little fortalice. In the feudal days of the Adhemars, ancestors of the Grignan family, who possessed the whole of the Comtat, these were probably the peel-houses, or outposts, of the old Chateau, in the quarter from which it would have been most exposed to attack. The Chateau Race-du-fort was, in all likelihood, also the key of the mountain glen leading to the hill which we were descending, and formed the line of communication with Montelimart, which was formerly included in the family territory. The records on this subject trace the foundation of the lordship of Grignan up to the days of Charlemagne, who is said to have created Adhemar,[17] one of his paladins, Duke of Genoa, as a reward for having re-conquered Corsica from the Saracens. Adhemar having fallen in a second expedition against the same enemy, his children divided his possessions: the elder remaining Duke of Genoa, another possessing the towns of St. Paul de Trois Chateau et Mondragon; and a third, the sovereignty of Orange. A fourth possessed the town of Monteil, called after him Monteil Adhemar, or Montelimart; and in 1160, the emperor Frederic I. granted to Gerard Adhemar de Monteil, his descendant and heir, the investiture of Grignan,
