Nor is the healthy simplicity of the period less marked in the selection than in the treatment of subjects. It has in these days become necessary for the painter who desires popularity to accumulate on his canvas whatever is startling in aspect or emotion, and to drain, even to exhaustion, the vulgar sources of the pathetic. Modern sentiment, at once feverish and feeble, remains unawakened except by the violences of gaiety or gloom; and the eye refuses to pause, except when it is tempted by the luxury of beauty, or fascinated by the excitement of terror. It ought not, therefore, to be without a respectful admiration that we find the masters of the fourteenth century dwelling on moments of the most subdued and tender feeling, and leaving the spectator to trace the under-currents of thought which link them with future events of mightier interest, and fill with a prophetic power and mystery scenes in themselves so simple as the meeting of a master with his herdsmen among the hills, or the return of a betrothed virgin to her house. [Illustration] It is, however, to be remembered that this quietness in character of subject was much more possible to an early painter, owing to the connection in which his works were to be seen. A modern picture, isolated and portable, must rest all its claims to attention on its own actual subject: but the pictures of the early masters were nearly always parts of a consecutive and stable series, in which many were subdued, like the connecting passages of a prolonged poem, in order to enhance the value or meaning of others. The arrangement of the subjects in the Arena Chapel is in this respect peculiarly skilful; and to that arrangement we must now direct our attention. [Illustration: INTERIOR OF THE ARENA CHAPEL, PADUA, LOOKING EASTWARD.] It was before noticed that the chapel was built between 1300 and 1306. The architecture of Italy in the beginning of the fourteenth century is always pure, and often severe; but this chapel is remarkable, even among the severest forms, for the absence of decoration. Its plan, seen in the marginal figure on p. 26, is a pure oblong, with a narrow advanced tribune, terminating in a trilateral apse. Selvatico quotes from the German writer Stieglitz some curious observations on the apparent derivation of its proportions, in common with those of other buildings of the time, from the number of sides of its apse. Without entering into these particulars, it may be noted that the apse is just one-half the width of the body of the chapel, and that the length from the extremity of the tribune to the west end is just seven times the width of the apse. The whole of the body of the chapel was painted by Giotto; the walls and roof being entirely covered either with his figure-designs, or with various subordinate decorations connecting and enclosing them.
