Chap. II. JACOBUS TORRITI. 93 The head of the Saviour, far from being of the inelegant form peculiar to the thirteenth century, has the simple outline of that in S. Costanza, or the apsis of S. Apol- linare in Classe at Ravenna with a fine flow of falling hair, a long full beard and regular features, and a simple nimbus of one line drawn on the blue background be decked with red clouds. It is a type and form which would have placed Torriti high in the ranks of the Chris tian imitators of the antique, but which differ essentially from those by the same mosaist in S. Maria Maggiore; nor would it be easy to maintain that the same artist could at one moment produce the Redeemer in the form of the fourth, fifth, or sixth centuries, and at another in that of the thirteenth. 1 Amongst the angels in the glory round the Saviour, one on the extreme right seems to have been renewed by Torriti. The head and mantle of S. Paul, the Virgin, S. John the Baptist, Nicolas the Fourth, S. Francis and S. Anthony are likewise renewed or introduced by him. 2 It is evident indeed that the three last mentioned personages are mere excrescences, not fitting the place they occupy, either in accordance with the laws of space, or the distribution of the older parts. As a concluding argument it may be observed that the mosaic bears not the least resemblance to the style of that executed by the monk Jacobus at Florence. Far different is the character of a mosaic forming a lower course to that of the semidome. Here, between the windows, and parted asunder by trees, are nine pro phets of square frame and broad neck, whose draperies in their cast, whose attitudes in their variety, and whose action in its expressiveness resemble those of the tribune in the Baptistery of Florence. On the lower border to the left is a miniature figure of an old Franciscan with a large compass and rule. On the lower border to the right * The head of the Saviour may have undergone repair, but if so maintains the character described, namely that of the imitation of the antique. 2 The figure of S. Andrew is I quite modern.
