roofed by
the successive overlapping or corbelling of the upper courses. The vault
thus formed is further supported by a pillar of wood or stone set in
the centre of the chamber. On the walls of some of the chambers there
are traces of rough painting in red. The whole tomb is covered with a
circular mound. In the best known example at Los Millares there are
remains of a semicircular facade in front of the entrance, as in many
other megalithic monuments.

The finest, however, of all the Spanish monuments is the corridor-tomb
of Antequera in Andalusia. It consists of a short passage leading into a
long rectangular chamber roofed with four slabs. Within it on its axial
line are three stone pillars placed directly under the three
meeting-points of the four slabs, but quite unnecessary for their
support. The whole tomb is covered with a low mound of earth. In the
great upright slab which forms the inner end of the chamber is a
circular hole rather above the centre.

It is not the plan of this tomb, but the size, that compels the
admiration of the beholder. He stands, as it were, within a vast cave
lighted only from its narrow end, the roof far above his head. The rough
surface of the blocks lends colour to the feeling that this is the work
of Nature and not of man. Here, even if not in Stonehenge, he will pause
to marvel at the patient energy of the men of old who put together such
colossal masses of stone.

Among the corridor-tombs of Spain must be mentioned a wedge-shaped type
which bears a close resemblance to those of Munster in Ireland (cf.
Fig. 7). In Alemtejo, south of Cape de Sines, are several of these,
usually about 6 feet in length, with a slight portico at one end.

A further point of similarity with the Irish monuments is seen in the
corridor-tombs of Monte Abrahao in Portugal, where the chamber walls
seem to have been reinforced by an outer lining of slabs. Remains of
eighty human bodies were found in this tomb, together with objects of
stone and bone, including a small conical button similar to that of
Carrowmore in Ireland.

The Spanish Peninsula also possesses rock-hewn tombs. At Palmella, near
Lisbon, is a circular example about 12 feet in diameter preceded by a
bell-shaped passage which slopes slightly downwards. Another circular
chamber in the same group has a much longer passage, which bulges out
into tw
