With Lysippos the development of art in its principal directions was terminated. As Overbeck says, “the summit lies behind us; we descend, and our way downwards may still lead through charming landscapes; but the pure, clear ether soon ceases to surround us, and, before the far-reaching glance, rises from the mist of centuries the flat and endless desert, in the sands of which the stream of Grecian art is quenched.” Alexander himself was the patron of the last of the seven great masters of sculpture; with him ended the fresh directness of Hellenic creations, as well as the greatness of Greece itself. He and his successors built temples afterwards to be furnished, as before, with statues of the deities and outwardly ornamented with sculptures; but they took their models from those earlier works which, elevated to a typical and canonical importance, were not to be surpassed, and employed themselves simply in reproducing. They followed more willingly the easy path open to them because, in the Alexandrian period, scepticism, empty formalism, and chilling indifference had already laid the ravaging axe to the Hellenic religion. With the spread of Hellenic power into the heart of Asia, its art, like its polity, lost its individuality, becoming expansive instead of intense, in decorative subjection to the requirements of elegance and use. Losing its former independent nobility, sculpture soon fell from the height which it had occupied for a century and a half. Athens, Sikyon, and Argos, hitherto central points of development, where art had brought forth its richest fruits as a model for the entire Hellenic world, now became provincial cities of the Macedonian kingdom, and lost their glory—some for a long period, and others forever. Following the example of Lysippos, artists preferred wandering from court to court of Alexander’s successors; and in Alexandria, Antioch, Seleucia, in Nicomedia, Pergamon, Ambrakia, mostly new and elegant cities of royal residence, occupation could not have been wanting, though the quantity of work may have tended to hasten the decline. How extensive and extravagant were the artistic requirements of the Diadochi, how excessive the incense of flattery offered them, is shown in the description of the luxurious works of the Ptolemies and of the Seleucidæ, and by the three hundred statues erected to Demetrius Phalereus in Athens alone. These last may have been somewhat better than the representation of the winds upon the clepsydra and vane of Andronicos Kyrrhestios (Figs. 233 and 234), but even they must be classed as mere artisan-work. Much was done in portrait-statuary after the time of Alexander, who turned art in this direction; and the successive dynasties also encouraged it, as may easily be imagined. This is evident from the statues still preserved, from the Ptolemaic cameos, and especially the coins of the Diadochi. The heads of these kings have never been equalled, for fine and lifelike characterization and modelling, in all the portrait coins and medallions which have been struck down to the present time. (Fig. 235.)
Though a great deal was produced in the period of the Diadochi, and, in the line of portraiture, much that was good, still there must have been truth in the saying of Pliny that “after the 121st Olympiad (290 B.C.) art ceased, and revived again only in the 156th (150 B.C.).” It ceased, namely, in so far as it was made subservient to courts and decoration; but upon the soil of Greece itself, and among the people, it grew, and strove after higher aims. The production continued, but its artisan-like elaboration did not make good the lost artistic originality. Men of vigorous talent followed in the paths of Praxiteles and Lysippos, producing works which are the ornaments of our antique collections; but the character of reproductions, clinging to their creations, robs them of the name of artist in the full sense of the word. The scanty notices of Pliny are, in general, correct; but he omits to mention some exceptions which represent a further development of sculpture, not quite unimportant, though questionable in principle.
In two places, at the royal court of Pergamon and in the republic of Rhodes, productive art rose again to a certain independence and originality. Pliny himself, in another place, says that “several artists illustrated the battles of Attalos and Eumenes against the Gauls; namely, Isigonos, Phycomachos, Stratonicos, and Antigonos.” The great victory over these barbarians was fought in 229 B.C. by Attalos, with which Eumenes, by a misunderstanding easily to be explained, appears to have been connected. Attalos erected in his capital a grand monument to his victory, and, not contenting himself with this, consecrated another upon the Acropolis at Athens, perhaps in part a copy of that in Pergamon. Remnants of both monuments still exist which give a comparatively good knowledge of the artistic peculiarities of this school. The investigations upon this site, now approaching completion, have unearthed hundreds of fragments in high-relief, part of a gigantomachia originally forming the decoration of an altar. The altar was surrounded by Ionic colonnades, the high stereobate of which was ornamented with sculptures in high-relief, the whole being elevated upon a gigantic terrace, 38 m. long, and 34 m. broad. The frieze, representing the gigantomachia, stands midway between the works of Lysippos and the Laocoon, and forms the most extensive and important monument of sculpture remaining from the time of the Diadochi; it is in many respects a parallel to that of the Mausoleum of Halicarnassos which represents the decorative work of the school of Scopas and Praxiteles. These works have now found their way to Berlin, but a critical account of them will be possible only when they shall have been made generally accessible by an official publication. The statue of the so-called Dying Gladiator of the Capitol belonged to the group in Pergamon already known (Fig. 236); as did the two figures in the Villa Ludovisi, representing a Gaul who, to escape the shame of slavery, has stabbed his wife, who sinks beside him, and is about to thrust the sword into his own neck. In the so-called Dying Gladiator, the rough hair growing low upon the neck, the strongly marked indentation between the brow and the projecting Northern nose, the beard shorn to the upper lip, the heavy cheek-bones, the fleshy and somewhat clumsily formed body, the hard and calloused skin upon the hands and feet, the twisted neckband, and the curved battle-horn have long since shown the meaning of this statue. In the group in the Ludovisi Villa, the same marble, a like and peculiar treatment of the forms, with the same type of head, leave no doubt that this also belonged to a large group representing a victory over the Gauls. From its style, it cannot be considered as a Roman monument, particularly as some notices of the Athenian Votive Offering of Attalos clearly identify it.
The most striking novelty in these monuments, and also in the school of art at Pergamon, is the characteristic following-out of ethnographical differences. Previously, when artists would distinguish barbarians, they were content to make the nationality clear by costume and accessories; but this could not suffice for Lysippos, who had carried individual characterization to such a height in his portrait-statues, and who probably, in his group of the battle upon the Granicos, illustrated the peculiarities of the Persian race. In groups of portrait-statues it was necessary to treat the action with absolute truthfulness, thus leading the way to historic art. This is perfected in the monument in question, the ideal battle scene being based upon real details; it was not merely a strife among men, but Greeks and Celts stood opposed, each nation with its marked features and peculiarities, the barbarians distinguished not outwardly alone, but by their natural wildness.
This is evident from a number of figures of the Athenian votive offering of Attalos, still preserved; our knowledge of their connection with the Dying Gladiator and the school of Pergamon is due to Brunn. According to Pausanias, this votive offering consisted of figures half the size of life, in four groups, showing the gigantomachia, the combat of the Amazons, the battle of Marathon, and the victory of Attalos. Figures exist from them all; from the first, a giant, dead and outstretched, is in the museum at Naples, as also one of the second, a fallen Amazon; from the third, a dead body clad in breeches, and two nude Persians kneeling, are in Naples, the Vatican, and in the possession of Signor Castellani. From the fourth, a kneeling figure, at Paris, and one kneeling and one falling backward, at Venice, are unmistakable Gauls; while a sitting figure, wounded, also at Venice, and a youthful one, dead, at Naples, are probably also of that race. Judging from these remains, the composition must have included numerous figures, as the five existing Gauls—perhaps also several more—bespeak a corresponding number at Pergamon, and forty is the lowest that can be reckoned for the whole. Their position was probably upon the steps of the monument, which possibly bore the statue of the founder. It must have stood near the wall of the Acropolis, since it has been said that a figure from the gigantomachia was thrown by a storm into the theatre which stood at the foot of this fortress. That only the conquered are found among the pieces preserved seems to be an evidence that these remnants are from the original rather than from any copy, because, aside from the improbability that so extensive a work would have been copied in later times, the effect of the storm suggests the thought that the erect statues of the victors would have been less likely to last through so many centuries than the lying and cowering figures, not so easily injured on account of their closer connection with the base. Notwithstanding their relation in style to the Capitoline statue and to the group in the Ludovisi Villa, these are distinctly inferior and harder. Brunn is probably right in his supposition that they are the work of scholars, and a contemporaneous reproduction from the studio of that master, who himself executed the monument at Pergamon, the figures of which ranked in merit with the Dying Gladiator. Many deficiencies may be accounted for by its reduction to half life-size; its repetition at this scale, for the Athenian votive offering, appearing to have satisfied the king.
The work most nearly related to this, also in marble, and perfectly similar in conception, is a figure of the Marsyas group, the celebrated Knife-sharpener in the Uffizi at Florence. This is also a representative of barbarism, probably a Scythian, the others having been Gauls; but, artistically, this makes no difference. No originals remain of the other figures in the group, of which the barbarian, cowering upon the ground and sharpening the knife for the flaying of Marsyas, probably formed no very important part. Another aim, the careful anatomical treatment of the body, is ostentatiously displayed in the copies of this work now in Berlin and Florence. The group suggests another locality, and forms a connecting medium between those two most important centres of art in that period, Pergamon and Rhodes.
