For some time after that it was the custom to draw in outline only, without any colouring, Pliny again being our authority. This was afterwards introduced by Philocles of Egypt with considerable pains, and also by Cleanthes and Ardices of Corinth and by Telephanes of Sicyon. Cleophantes of Corinth was the first of the Greeks to use colours, and Apollodorus was the first to introduce the brush. Polignotus of Thasos, Zeuxis and Timagoras of Chalcis, Pythia and Aglaphon followed them, all most celebrated, and after them came the renowned Apelles who was so highly esteemed and honoured for his skill by Alexander the Great, for his wonderful delineation of Calumny and Favour, as Lucian relates. Almost all the painters and sculptors were of high excellence, being frequently endowed by heaven, not only with the additional gift of poetry, as we read in Pacuvius, but also with that of philosophy. Metrodorus is an instance in point, for he was equally skilled as a philosopher and as a painter, and when Apelles was sent by the Athenians to Paulus Emilius to adorn his triumph he remained to teach philosophy to the general's sons. Sculpture was thus generally practised in Greece, where there flourished a number of excellent artists, among them being Phidias of Athens, Praxiteles and Polycletus, very great masters. Lysippus and Pyrgoteles who were of considerable skill in engraving, and Pygmalion in ivory carving in relief, it being recorded of him that he obtained life by his prayers for the figure of a maid carved by him. The ancient Greeks and Romans also honoured and rewarded painting, since they granted the citizenship and very liberal gifts to those who excelled in this art. Painting flourished in Rome to such an extent that Fabius gave a name to his house, subscribing himself in the beautiful things he did in the temple of safety as Fabius the painter. By public decree slaves were prohibited from practising painting, and so much honour was continually afforded by the people to the art and to artists that rare works were sent to Rome among the spoils to appear in the triumphs; excellent artists who were slaves obtained their liberty and received notable rewards from the republic. The Romans bore such a reverence for the art that when the city of Syracuse was sacked Marcellus gave orders that his men should treat with respect a famous artist there, and also that they should be careful not to set fire to a quarter in which there was a very fine picture. This was afterwards carried to Rome to adorn his triumph. To that city in the course of time almost all the spoils of the world were brought, and the artists themselves gathered there beside these excellent works. By such means Rome became an exceedingly beautiful city, more richly adorned by the statues of foreign artists than by those made by natives. It is known that in the little island city of Rhodes there were more than 30,000 statues,
