heights, comparatively free from all buildings except their own proper companions. But there is not the wide, open space around them which surrounds the church of Alatri. One cannot help wishing that some more worthy building, either the primæval temple itself or some more fitting successor, occupied so noble a site, a site in truth which needs--let us say either the Parthenôn of Athens or the Parthenôn of Lincoln to do it justice. But the only thing that can be said for the cathedral church of Alatri is that the lower part of its wall is part of the _cella_ of the primæval temple. Here we have something even more than can be seen at Segni. We know not what may have been added in the way of a pillared front; but it is plain that, as far as the main walls are concerned, the building which was transformed into a Christian church was actually the house of pagan worship itself. And it was a house going back, not to dated Emperors or consuls, but to the unrecorded age which reared these cities great and fenced up to heaven. There is the terrace, there is the wall of the _cella_, wrought of the same wonderful masonry as the walls of the surrounding _arx_, as the walls of the yet again surrounding city. It is strange indeed to see the ordinary rites of Christian worship, the ordinary accompaniments of a Christian church, dwelling, as at Rome and Syracuse, within the temples of a creed, fallen indeed but perfectly familiar. But here we see them within walls reared in honour of we know not what--gods of unchronicled days, gods alongside of whom Jupiter of the Capitol may have seemed as strange and foreign as Mithras and Serapis now seem alongside of Jupiter of the Capitol.
