an object deserving the study of future architects, which a handsomer building might not have been. Singularity often merits examination, when it by no means deserves imitation. A little church in the shape of a cross, dedicated to Sts. Nazarus and Celsus, forms the Sepulchre of Galla Placidia, who built it in her lifetime. It is about 40 feet long, and 32 in the transept; the arms being about 14 feet wide. The walls were once covered with marbles; these have disappeared, but all the vaulting is still covered with figures and arabesques in mosaic. On each side of the nave a plain marble sarcophagus is incrusted in the wall; and there is a larger one, adorned with sculpture, at each end of the transept; but the largest of all, which stands at the head of the cross, and once contained the bones of the empress herself, is quite plain, having been, as is supposed, originally covered with metal. There is said to have been a small window at the back of this chest, through which, in 1577, some children put a lighted candle, and the clothes and body of the empress were thereby consumed; on which account it was shut up; but I could discern no trace of its existence. [Illustration: A.B. Clayton. del. from Sketches by J. Woods. TOMB OF THEODERIC. ] A far more curious tomb is that of Theodoric, which stands a little way out of Ravenna. The building is decagonal below, and circular on the upper part: the decagon of the basement is somewhat larger than the superior edifice. Each face has a deep recess, covered with a semicircular arch, whose stones are notched into one another. This basement is now half buried, and the water stands in it: an oblique flight of steps on each side of the division which faces the approach, conducts us to the upper story. This has also ten sides externally on the lower part, but is circular within. Each side, except that which contains the door, has two square-headed recesses, and each recess is placed under an arch, the support of which is not carried down to the ground, but projects from the face of the work. In front of these recesses and arches, tradition says that there has been a range of columns, but I could discern no certain traces of such an ornament, and the space to receive them, arising from the projection of the basement beyond the upper part of the edifice, is very narrow for such a purpose. The work looks unfinished, and I have no doubt that something more than what at present exists was either executed or intended, but I cannot form any probable conjecture of what it was. Immediately over these arches there is a broad circular band, above which all the work is circular. This band is interrupted by the vault-stones, forming a straight arch above the door, which are very curiously notched together, and there is nevertheless a small opening between these and the cornice and architrave below, made in order that the latter might not be in any danger of being broken by the settlement of the arch.
