According to CastaldiE. (“Tombe di Giganti nel Sassarese”, Origini, iii (1969), 119–274, pp. 251–6, Appendix I), some 219 true tdgs were known at the time of writing. By adopting a looser definition (one inappropriate to our present purposes), LilliuG. (La civiltà dei Sardi (2nd edn, Turin, 1975)) arrived at a total of 321. All the 78 tombs discussed here fall within the stricter definition, so that our survey covers more than one in three of the tdgs known in 1969, a number of which have been destroyed since.

The late L. Pericot García, who was a leading authority on the Balearic Islands, remarks in The Balearic Islands (London, 1972), 79: “The ‘giants’ tombs' of Sardinia have always been mentioned as possible prototypes for navetas, for the building techniques employed are similar.” As we shall see, this last remark is questionable. There is a preliminary discussion of this problem in Hoskin and NúñezMorales, op. cit. (ref. 1), S35–39.
This is, for example, the view of ManconiD. and PianuG., Sardegna, 2nd edn (Rome, 1990), 152, and of ContuErcole, “Edificio megalitico rettangolare di Domu de Orgia in località Cuccureddi”, Studi Sardi, viii (1948), 313–17.

LilliuGiovanni, La civilità nuragica (Sassari, 1982), 12, 106–11; cf. the discussion in his La civiltà dei Sardi, 2nd edn (Turin, 1975), 328. Lilliu now suggests the ‘megaron’ temples may be fourteenth or thirteenth century. From the Tempietto di Malchittu there is a radiocarbon date from the hearth that shows it was in use early in the first millennium b.c. (see ref. 18 below).

One must consider the possibility that the orientation in the minds of the builders was in the opposite direction, from the outside looking in. Only in the larger temple at Serra Orrios does the wall opposite the entrance survive to a considerable height (see Figure 13); it happens that this wall, exceptionally, is curved on the outside (as the figure shows) and straight on the inside, and so for the most part is very thick, and a substantial opening in it is hard to imagine. We might also note that in the case of the temple near Alà dei Sardi (on which see below), an orientation from the entrance towards the closed end would be directed immediately into a very steep upward slope, and this seems implausible. As already mentioned, the orientation of the tdgs is unquestionably from the inside looking out through the entrance, for these tombs are frequently located on the very edge of a high plateau in such a way that the entrance looks out over the valley below.
