That a strong passion for portraits formerly existed, is attested both by Atticus, the friend of Cicero, who wrote a work on this subject, and by Varro, who conceived the very liberal idea of inserting, by some means or other, in his numerous volumes, the portraits of seven hundred individuals; as he could not bear the idea that all traces of their features should be lost, or that the lapse of centuries should get the better of mankind. Thus was he the inventor of a benefit to his fellow-men, that might have been envied by the gods themselves; for not only did he confer upon them immortality, but he transmitted them to all parts of the earth; so that it might be possible for them to be present, everywhere and each occupy his niche. This service Varro conferred upon persons who were not members of his own family. CHAPTER XIV. THE EARLIEST PAINTERS. We have no certain knowledge as to the commencement of the art of painting. The Egyptians assert that it was invented among themselves, six thousand years before it passed into Greece; a vain boast—evidently. As to the Greeks, some say that it was invented at Sicyon, others at Corinth; but they all agree that it originated in tracing lines round the human shadow. The first stage of the art was this, the second the employment of single colors; a process known as “monochrome-painting.” The invention of line-drawing has been assigned to Philocles, the Egyptian, or to Cleanthes of Corinth. The first who practised this line-drawing were Aridices, the Corinthian, and Telephanes, the Sicyonian, artists who, without making use of any colors, shaded the interior of the outline by drawing lines; hence, it was the custom with them to add to the picture the name of the person represented. Ecphantus, the Corinthian, was the first to employ colors upon these pictures, made, it is said, of broken earthenware, reduced to powder. But already had the art of painting been perfectly developed in Italy. At all events, there are extant in the temples at Ardea, at this day, paintings of greater antiquity than Rome itself; in which, in my opinion, nothing is more marvellous, than that they should have remained so long unprotected by a roof, and yet preserving their freshness. At Lanuvium we see an Atalanta and a Helena, without drapery, close together, and painted by the same artist. They are both of the greatest beauty, the former being evidently the figure of a virgin, and they still remain uninjured, though the temple is in ruins. The Emperor Caligula attempted to have them removed to his own palace, but the nature of the plaster would not admit of it. There are in existence at Cære, some paintings of a still higher antiquity. Whoever carefully examines them, will be forced to admit that no art has arrived more speedily at perfection, seeing that it evidently was not in existence at the time of the Trojan War.
