The pottery of the megalithic area is not all alike; it would be surprising if it were.  Even supposing that the invaders brought with them a single definite style of pottery-making this would rapidly become modified by local conditions and by the already existing pottery industry of the country, often, no doubt, superior to that of the new-comers.  Nevertheless, there are a few points of similarity between the pottery of various parts of the megalithic area.  The most remarkable example is the bell-shaped cup, which occurs in Denmark, England, France, Spain, Sardinia, and possibly Malta (the specimen is too broken for certainty).  Outside the area it is found in Bohemia, Hungary, and North Italy.  Here, as in the case of the conical button, we cannot argue that the form was actually introduced by the megalithic race, though there is a certain possibility in favour of such a hypothesis.

That the megalithic people possessed a religion of some kind will hardly be doubted.  Their careful observance of the rites due to the dead, and their construction of buildings which can hardly have been anything but places of worship, is a strong testimony to this.  We have seen that in the Maltese temples the worship of baetyls or pillars of stone seems to have been carried on.  Several stone objects which can scarcely have been anything but baetyls were found in the megalithic structures of Los Millares in Spain, but none are known elsewhere in the megalithic area.

There is some reason for thinking that among the megalithic race there existed a cult of the axe.  In France, for instance, the sculptured rock-tombs of the valley of the Petit Morin show, some a human figure, some an axe, and some a combination of the two.  This same juxtaposition of the two also occurs on a slab which closed the top of a corbelled chamber at Collorgues in Gard.  A simple allee couverte at Goehlitzsch in Saxony has on one of its blocks an axe and handle engraved and coloured red.  There are further examples in the allee couverte of Gavr’inis and the dolmen called La Table des Marchands at Locmariaquer.

These sculptured axes call to mind at once the numerous axe-shaped pendants of fine polished stone (jade, jadeite, etc.) found in Malta, Sicily, Sardinia, and France, and apparently used as amulets.  The excavation of Crete has brought to light a remarkable worship of the double axe, and it has been argued with great probability that one of the early boat signs figured on the pre-dynastic painted vases of Egypt is a double axe, and that this was a cult object.  It seems very probable that in the megalithic area, or at least in part of it, there was a somewhat similar worship, the object of cult, however, being not a double but a single axe, usually represented as fitted with a handle.  It need not be assumed that the axe itself was worshipped, though this is not impossible; it is more likely that it was an attribute of some god or goddess.
