OTHING in the ancient history of man is of more considerable interest than are those monuments, at once rudely grand and mysteriously simple, which have been designated megalithic. They may be simply raised stones, isolated menhirs, cromlechs arranged in a circle, or artificial caves formed by placing flat flags horizontally on standing supports. Dolmens or covered passages were usually buried under masses of earth or stones, so as to form veritable tumuli; but they always present the common character of being constructed in rough blocks, virgin of all human labor.
Megaliths are important on account of their number[1] and their dispersion. They are to be found, with a likeness running through them all, in places most remote from one another, on different continents. At Carnac and at Kermarin are immense rows of stones, of which the menhirs of the Khasias of India appear like exact copies. Similar dolmens are standing in Palestine, Ireland, and Hindostan. Megaliths can be found in Peru and among the aboriginal monuments of North America, in Spain and Denmark, in the Orcades and the islands of the Mediterranean, on the shores of the Black Sea and of the Baltic, at the foot of Mount Sinai, and in Iceland a⏩
M. Cartailhac, for many years editor of the "Materiaux pour servir à l'Histoire de l'Homme" ("Materials to be used for the History of Man"), has, in a recent book on "Prehistoric Ages in Spain and Portugal" ("Les Ages préhistoriques en Espagne et en Portugal"), described some remarkable monuments in the Iberian Peninsula, most of which have not been previously brought to the scientific attention of students in other countries. The megaliths of Portugal consist in a great part of dolmens, or antas, as the⏩
y are called there. Three hundred and fifteen of them were known in 1754. Some of them have disappeared; but though Pereira de Costa could report upon only thirty-nineIn every country the rocks are disintegrated by the effect of weather-changes into large blocks. The megalith-builders chose those blocks for their purpose which offered the fairest surface. The inclosure was hollowed out. The stones chosen for the walls of the burial-chamber were raised, planted in the soil, and covered with large flat stones; and then the interstices were filled up with pebbles. A low, narrow entrance-gallery was made by a similar method, and, after the funeral rites were performed, the crypt was covered with a tumulus—a protecting envelope which has in most cases been removed long ago under the impulse of curiosity or with the hope of finding hidden
treasures. The few dolmens still buried are called mammoas or maminhas (mammæ), from their peculiar form.These antas frequently served for a considerable number of burials each, and in that case the entrance-gallery seems to have been kept open. At other times, a single corpse was deposited, and the crypt was closed, as the friends thought, forever.
Notwithstanding it has suffered considerable mutilations, the crypt of the great
ollected from it, together with fine specimens of flint-flakes, retouched on the edges, and of triangular points, three vases covered with ornaments, and forty-three hatchets, nearly all of diorite, and remarkable specimens of work. Some human bones lay in the midst of these memorials of human wealth. Unfortunately, they have been scattered.
We can not leave the antas of Portugal without mentioning the bowls which M. Cartailhac observed on some of the megaliths of Alemtejo. Such vessels have long been known in prehistoric archaeology. They are found in Switzerland, in the Pyrenees, in Brittany, in Scotland, in Scandinavia, and on the rocks of Hindostan. The bowls, engraved on the walls of some of the crypts, recently disengaged from their earthy envelope, have doubtless, as M. Cartailhac observes in relating his discovery, an indisputable antiquity, value, and meaning; but we can not determine the age, and the value and meaning are unknown to us. Megaliths are especially abundant in Estremadura, the richest province in Roman Spain, nowollected from it, together with fine specimens of flint-flakes, retouched on the edges, and of triangular points, three vases covered with ornaments, and forty-three hatchets, nearly all of diorite, and remarkable specimens of work.
