[233] Far more fruitful still was the invention of casting, of casting hollow figures especially, attributed to Rhoecus and Theodorus, architects of the great temple at Samos. Such hollow figures, able, in consequence of their lightness, to rest, almost like an inflated bladder, on a single point--the entire bulk of a heroic rider, for instance, on the point of his horse's tail--admit of a much freer distribution of the whole weight or mass required, than is possible in any other mode of statuary; and the invention of the art of casting is really the discovery of liberty in composition.* And, at last, about the year 576 B.C., we come to the first true school of sculptors, the first clear example, as we seem to discern, of a communicable style, reflecting and interpreting some real individuality (the double personality, in this case, of two brothers) in the masters who evolved it, conveyed to disciples who came to acquire it from distant places, and taking root through them at various centres, where the names of the [234] masters became attached, of course,. to many fair works really by the hands of the pupils. Dipoenus and Scyllis, these first true masters, were born in Crete; but their work is connected mainly with Sicyon, at that time the chief seat of Greek art. "In consequence of some injury done them," it is said, "while employed there upon certain sacred images, they departed to another place, leaving their work unfinished; and, not long afterwards, a grievous famine fell upon Sicyon. Thereupon, the people of Sicyon, inquiring of the Pythian Apollo how they might be relieved, it was answered them, 'if Dipoenus and Scyllis should finish those images of the gods'; which thing the Sicyonians obtained from them, humbly, at a great price." That story too, as we shall see, illustrates the spirit of the age. For their sculpture they used the white marble of Paros, being workers in marble especially, though they worked also in ebony and in ivory, and made use of gilding. "Figures of cedar-wood, partly incrusted with gold"--kedrou zôdia chrysô diênthismena+--Pausanias says exquisitely, describing a certain work of their pupil, Dontas of Lacedaemon. It is to that that we have definitely come at last, in the school of Dipoenus and Scyllis. Dry and brief as these details may seem, they are the witness to an active, eager, animated period of inventions and beginnings, in which the Greek workman triumphs over the first [235] rough mechanical difficulties which beset him in the endeavour to record what his soul conceived of the form of priest or athlete then alive upon the earth, or of the ever-living gods, then already more seldom seen upon it. Our own fancy must fill up the story of the unrecorded patience of the workshop, into which we seem to peep through these scanty notices--the fatigue, the disappointments, the steps repeated, ending at last in that moment of success, which is all Pausanias records, somewhat uncertainly.
