PREFACE
have ceased to be occupied, but the Maqui, in North-West Arizona, still inhabit villages of stone built on sandstone tables, standing isolated in the midst of a sandy ocean almost destitute of vegetation.
The cause of the abandonment of the cliff dwellings has been the diminished rainfall, that rendering the land barren has sent its population elsewhere. The rivers, the very streams, are dried up, and only parched water-courses show where they once flowed.
"The early inhabitants of the region under notice were wonderfully skilful in turning the result of the natural weathering of the rocks to account. To construct a cave- dwelling, the entrance to the cave or the front of the open gallery was walled up with adobes, leaving only a small opening serving for both door and window. The cliff houses take the form and dimensions of the platform or ledge from which they rise. The masonry is well laid, and it is wonderful with what skill the walls are joined to the cliff, and with what care the aspect of the neighbouring rocks has been imitated in the external architecture."[1]
In Asia also these rock-dwellings abound. The limestone cliffs of Palestine are riddled with them. They are found also in Armenia and in Afghanistan. At Bamian, in the latter, "the rocks are perforated in every direction. A whole people could put up in the 'Twelve Thousand Galleries' which occupy the slopes of the valley for a distance of eight miles. Isolated bluffs are pierced with so many chambers that they look like honeycombs."[2]
That Troglodytes have inhabited rocks in Africa has been known since the time of Pliny.
But it has hardly been realised to what an extent similar cliff dwellings have existed and do still exist in Europe.
