Dolmens (probably to be regarded as a simpler form of the tomba dei giganti, inasmuch as specimens with chambers elongated after their first construction have been found) and menhirs are also present in Sardinia, though the former are very rare - that known as Sa Perda e S'altare, near the railway to the south of Macomer is illustrated by A.

The question as to whether copper really was first used in Egypt is not yet resolved, and many arguments can be brought against the theory of Egyptian origin and in favour of one in Syria or further north.26 Egypt has also recently been credited with being the inceptor of the whole " megalithic (or heliolithic, as the fashionable word now is) culture " of mankind, from Britain to China and (literally) Peru or at any rate Mexico via the Pacific Isles.27 The theory is that the achievements of the Egyptians in great stone architecture at the time of the pyramid-builders so impressed their contemporaries that they were imitated in the surrounding lands, by the Libyans and Syrians, that the fame of them was carried by the Phoenicians further afield, and that early Arab and Indian traders passed on the megalithic idea to Farther India, and thence to Polynesia and so on so that both the teocalli of Teotihuacan and Stonehenge are ultimately derived through cromlechs and dolmens innumerable from the stone pyramid of Saqqara, built by Imhotep, the architect of King Zoser, about 3100 B.C. (afterwards deified as the patron of science and architecture).

Navigation could be carried on, or the lake-dwellings themselves be erected, without the use of ropes and cords; and the erection of memorial stones (menhirs, dolmens), at whichever era, and to whatever people these monuments may belong, would be altogether impracticable without the use of strong ropes."
