In this monument, then, we have a revelation in the sphere of art, of the temper which made the victories of Marathon and Salamis possible, of the true spirit of Greek chivalry as displayed in the Persian war, and in the highly ideal conception of its events, expressed in Herodotus and approving itself minutely to the minds of the Greeks, as a series of affairs in which the gods and heroes of old time personally intervened, and that not as mere shadows. It was natural that the high-pitched temper, the stress of thought and feeling, which ended in the final conflict of Greek liberty with Asiatic barbarism, should stimulate quite a new interest in the poetic legends of the earlier conflict between them in the heroic age. As the events of the Crusades and the chivalrous spirit of that period, leading men's minds back to ponder over the deeds of [261] Charlemagne and his paladins, gave birth to the composition of the Song of Roland, just so this Aeginetan sculpture displays the Greeks of a later age feeding their enthusiasm on the legend of a distant past, and is a link between Herodotus and Homer. In those ideal figures, pensive a little from the first, we may suppose, with the shadowiness of a past age, we may yet see how Greeks of the time of Themistocles really conceived of Homeric knight and squire. Some other fragments of art, also discovered in Aegina, and supposed to be contemporary with the temple of Athene, tend, by their roughness and immaturity, to show that this small building, so united in its effect, so complete in its simplicity, in the symmetry of its two main groups of sculpture, was the perfect artistic flower of its time and place. Yet within the limits of this simple unity, so important an element in the charm and impressiveness of the place, a certain inequality of design and execution may be detected; the hand of a slightly earlier master, probably, having worked in the western gable, while the master of the eastern gable has gone some steps farther than he in fineness and power of expression; the stooping figure of the supposed Ajax,--belonging to the western group in the present arrangement, but really borrowed, as I said, from the eastern,--which has in it something above the type of the figures grouped round it, being this later sculptor's work. Yet Overbeck, [262] who has elaborated the points of this distinction of styles, commends without reserve the technical excellence of the whole work, executed, as he says, "with an application of all known instruments of sculpture; the delicate calculation of weight in the composition of the several parts, allowing the artist to dispense with all artificial supports, and to set his figures, with all their complex motions, and yet with plinths only three inches thick, into the basis of the gable; the bold use of the chisel, which wrought the shield, on the freely-held arm, down to a thickness of scarcely three inches;
