Plastic Art in Italy
The plastic and delineative arts are more recent than architecture; the house must be built before any attempt is made to decorate gable and walls. It is not probable that these arts really gained a place in Italy during the regal period of Rome; it was only in Etruria, where commerce and piracy early gave rise to a great concentration of riches, that art or handicraft--if the term be preferred--obtained a footing in the earliest times.
Greek art, when it acted on Etruria, was still, as its copy shows, at a very primitive stage, and the Etruscans may have learned from the Greeks the art of working in clay and metal at a period not much later than that at which they borrowed from them the alphabet. The silver coins of Populonia, almost the only works that can be with any precision assigned to this period, give no very high idea of Etruscan artistic skill as it then stood; yet the best of the Etruscan works in bronze, to which the later critics of art assigned so high a place, may have belonged to this primitive age; and the Etruscan terra-cottas also cannot have been altogether despicable, for the oldest works in baked clay placed in the Roman temples--the statue of the Capitoline Jupiter, and the four-horse chariot on the roof of his temple--were executed in Veii, and the large ornaments of a similar kind placed on the roofs of temples passed generally among the later Romans under the name of "Tuscanic works."
