Another famous work of decorative sculpture belonging to this period is the colossal group of the Niobids. It was brought to Rome from somewhere in Asia Minor, probably Cilicia, and apparently copied by several Græco-Roman artists of very various powers. The original dates, no doubt, from the fourth century. It seems to have formed a group of detached statues set up on a pedestal either in the open air or in a colonnade. The general arrangement of the figures resembles that of a pedimental composition, for the whole group would be pyramidal, with Niobe herself as the apex figure. Niobe’s tragedy is an example of divine jealousy aroused by excessive human felicity and pride, for Niobe was so proud of the beauty of her large family that she exulted over Leto, who had but two children, Apollo and Artemis. Accordingly she and all her brood were shot down by the painless arrows of the two gods. The “plot” of the group is a study in psychology, typical of the fourth century, showing how the various members of the doomed family met their deaths. Here again the technique is wonderful; every figure is designed in a broad architectural spirit. The actual figures, as we have them, mostly at Florence, are of varying merit. Probably the best is the most recently discovered, which is here illustrated.[100] But all are of rather frigid perfection in workmanship. [Illustration: PLATE LXXIV. STATUE OF MAUSOLUS, FROM THE MAUSOLEUM _Mansell & Co._] THE OTHER ARTS Nothing has been said here about painting, because Greek painting is essentially a matter for the professional archæologist who can study what Pliny and others said about it and try to find some intelligent meaning in it by reference to pottery and sculpture. Of course the influence of Polygnotus, Parrhasios, Zeuxis, and Apelles should be traceable even in the humble decorators of pitcher, pot, and pipkin. But we have no relics of the original work of any of those artists, and the ancient art critic is an obscure and uncertain guide. He seems to have had the most ridiculous canons of art, and to have considered it the greatest triumph of painting when birds came to peck at the grapes in a picture. The only Greek pictures that we have are the mural frescoes and mosaics of Pompeii, which belong properly to the Roman department, and a few Egyptian mummy-cases painted by Greek artists. Therefore, if you please, we will leave Greek painting to the connoisseurs, with the remark that Apelles of the fourth century was considered the greatest of all Greek masters.
