273. Church of the Nativity at Bethlehem. (From Bernardino Amico.) Scale 100 ft. to 1 inch.
Of the former class one of the most authentic and perfect is that erected at Bethlehem by Helena, the mother of Constantine, in front of the cave of the Nativity. The nave seems to be a nearly unaltered example of this age, with the advantage over the contemporary churches at Rome, that all its pillars and their capitals were made for the places they occupy, whereby the whole possesses a completeness and justness of proportion not found in the metropolis. Its dimensions, though sufficient for effect, are not large, being internally 103 ft. across, by 215 ft. east and west. The choir with its three apses does not seem to be part of the original arrangement, but to have been added by Justinian when he renovated—Eutychius says rebuilt—the church. My impression is that a detached circular building, external to the basilica, originally contained the entrance to the cave. The frescoes were added apparently in the 11th or 12th century.[[218]]
One of the principal points of interest connected with this church is, that it enables us to realise the description Eusebius gives us of the basilica which Constantine erected at Jerusalem in honour of the Resurrection. Like this church it was five-aisled, but had galleries; the apse also was on a larger scale than could well have been possible in the Bethlehem church, and adorned with twelve pillars, symbolical of the Apostles.
Of this building nothing now remains, and the only portion which could be claimed as part of Constantine’s work is the western wall of the Rotunda, which to a height of 15 to 20 ft. was cut out of the solid rock in order to isolate the Holy Sepulchre in the centre. The so-called tombs of Absalom and Zachariah in the valley of Jehoshaphat were detached in a similar way from the rock behind them.[[219]]
Thessalonica.
274. Eski Djuma, Thessalonica. (From Texier and Pullan.) Scale 100 ft. to 1 in.
As before mentioned, it is to Constantinople, or Alexandria, or Antioch, that we should naturally look to supply us with examples of the style of the early transition, but as these fail, it is to Thessalonica alone—in so far as we now know—that we can turn. In that city there are two ancient examples. One, now known as the Eski Djuma or old mosque (Woodcut No. [274]), may belong to the 5th century, though there are no very exact data by which to fix its age. It consists of a nave, measuring, exclusive of narthex and bema, 93 ft. across by 120 ft.—very much the proportion of the Bethlehem church, but having only three aisles, the centre one 48 ft. in width. The other church, that of St. Demetrius, is larger, but less simple. It is five-aisled, has two internal transepts, and various adjuncts. Altogether it seems a considerable advance towards the more complicated form of a Christian church. Both these churches have capacious galleries, running above the side aisles, and probably devoted to the accommodation of the women. The date of St. Demetrius is most probably among the first years of the sixth century.[[220]] The general ordinance of the columns will be understood from the woodcut (No. [276]). Generally they are placed on elevated square or octagonal bases, or pedestals, as in the tepidaria of the Thermæ in Rome, and all have a block (known as the dosseret), placed above the capital, which is supposed to represent the entablature of the Roman example, but is probably an original feature inserted over the capital to support the springing of the arch. In this form it is found very generally in the 5th and 6th centuries, after which it fell into disuse, an increased depth being given to the abacus of the capital to take its place.
