The second explanation is perhaps the more probable. Mackenzie seems to adopt it, and fancies that in the growth of the largest nuraghi we may trace the rise to power of some of these local dynasts at the expense of their neighbours. He suggests that the existence of the fortified enclosure of Nossiu, where there is no sign of a true nuraghe, may mean that there were certain communities which succeeded in maintaining their independence in the face of these powerful rulers. But here, as he himself is the first to admit, we are in the realm of pure conjecture.

Giant's Tomb at Muraguada, Sardinia. (Mackenzie, Papers of the British School of Rome, V.) |
It is now established that in the Giants' Tombs of Sardinia we are to see the graves of the inhabitants of the nuraghe villages. Every Giant's Tomb lies close to such a village, and almost every village has its Giants' Tombs, one or more in number according to its size. A Giant's Tomb consists of a long rectangular chamber of upright slabs roofed by corbelled masonry (Fig. 18). The slab which closes one end of the tomb is of great size, and consists of a lower rectangular half with a small hole at the base and an upper part shaped like a rounded gable. There is a raised border to the whole slab, and a similar band in relief marks out the two halves. This front slab forms the centre-piece in a curved façade of upright slabs. The chamber is covered with a coating of ashlar masonry, which is shaped into an apsidal form at the end opposite to the façade. Occasionally more than 50 feet in length, the Giants' Tombs served as graves for whole families, or even for whole villages. Mackenzie has shown that the form is derived from the simple dolmen, and has pointed out several of the intermediate stages.
The inhabitants of Sardinia in the megalithic period also buried their dead in rock-hewn sepulchres, of which there are numerous examples at Anghelu Ruju. The contents of these graves make it clear that they are the work of the same people as the Giants' Graves. Were further proof needed it could be afforded by a grave at Molafà, where a Giant's Grave with its façade and gabled slab has been faithfully imitated in the solid rock. There is a similar tomb at St. George. Two natural caves in Cape Sant' Elia on the south of the island contain burials of this same period.
The neighbouring island of Corsica also contains important megalithic remains. They consist of thirteen dolmens, forty-one menhirs, two alignements, and a cromlech. They fall geographically into two groups, one in the extreme north and the other in the extreme south of the island.
The stones used are chiefly granite and gneiss. The dolmens, which are of carefully chosen flat blocks showing no trace of work, are all rectangular in plan, and usually consist of four side-walls and a cover-slab. The finest of all, however, the dolmen of Fontanaccia, has seven blocks supporting the cover, one at each short end, three in one of the long sides, and two in the other. None of the dolmens are covered by mounds.
Of the alignements, that of Caouria seems to consist, in part at least, of two parallel lines of menhirs, the rest of the plan being uncertain. There are still thirty-two blocks, of which six have fallen. The other alignement, that of Rinaiou, consists of seven menhirs set in a straight line. The cromlech is circular and stands on Cape Corse.
On the small island of Pianosa, near Elba, are several rock-hewn tombs of the æneolithic period which ought perhaps to be classed with the megalithic monuments of Sardinia and Corsica.
