In Brittany we find the Menhirs or "standing stones," unhewn pillars, regularly accompanying the dolmens. They are by far most abundant in northwestern Europe, but occur elsewhere also. The largest known is the Menhir of Locmariaquer in Morbihan, now fallen and broken. It was almost 21 metres long, and weighed nearly 300,000 kilograms. But specimens are usually much smaller. They seem to characterize the Æneolithic Epoch and the early Bronze Age. Their meaning is often uncertain. Some of them standing singly were probably erected much later, serving merely to mark boundaries. When associated with dolmens they are probably objects of a religious cult associated with the burial, rather than mere monuments to the dead. They may well be examples of the world-wide pillar-cult. They remained objects or centres of worship until late in historic time. The church had a long and hard battle with their cult. Some of them appear to have been thrown down and churches to have been erected over them. On some of them Christian symbols have been carved. Among the people they are still held in reverence or awe. Whatever may have been their origin, they must have had some religious significance or association. These pillars may be grouped in circles, cromlechs, or in long radiating rows, alignments. Stone circles occur in the Mediterranean region, in Syria, Upper Egypt, and in India. But circles and alignments belong especially to Brittany, Great Britain, and Scandinavia. The most noteworthy are the three adjacent or connected at Carnac, in Morbihan, extending nearly 4,000 metres, and composed of nearly 3,000 Menhirs. Stonehenge and Avebury in England are almost equally celebrated. They represent the culmination of megalithic development, but are essentially places of worship and assembly rather than of burial, though tumuli may be clustered around them like graves in a churchyard. The changes in the mode of disposal of the dead are evidently the results of changed views concerning the future life. In early Paleolithic times man buried his dead with the best flint axe in his hand, with his ornaments and a supply of food, and often a quantity of shells brought from a distance and evidently objects of value. The dead man took with him his weapons and all his wealth. For the living to keep back a portion of what belonged to the departed was robbery, which might be avenged by all sorts of evils and plagues; for all this material wealth and ornament was as much needed and as useful there as here. Apparently, though this is anything but certain, the dead were buried at first in Europe, extended at full length, and in the caves not far from the abode of the living.
