Protogenes (; ; fl. 4th century BC) was an ancient Greek painter, a contemporary rival of Apelles. As with the other famous ancient Greek painters, none of his work has survived, and it is known only from literary references and (brief) descriptions. Biography Protogenes was born in Caunus, on the coast of Caria but resided in Rhodes during the latter half of the 4th century BC. He was celebrated for the minute and laborious finish which he bestowed on his pictures, both in drawing and in color. Apelles, his great rival, standing astonished in presence of one of these works, could console himself only by saying that it was wanting in charm. Pliny the Elder, in his Natural History, relates the story of a contest between Apelles and Protogenes: 'Apelles sailed [to Rhodes], eager to see the works of a man known to him only by reputation, and on his arrival immediately repaired to the studio. Protogenes was not at home, but a solitary old woman was keeping watch over a large panel placed on the easel. In answer to the questions of Apelles, she said that Protogenes was out and asked the name of the visitor. "Here it is," said Apelles, and snatching up a brush he drew a line of extreme delicacy across the board. On the return of Protogenes, the old woman told him what had happened. When he had considered the delicate precision of the line he at once declared that his visitor had been Apelles, for no one else could have drawn anything so perfect. Then in another colour he drew a second still finer line upon the first, and went away, bidding her show it to Apelles if he came again, and add that this was the man he was seeking. It fell out as he expected; Apelles did return, and, ashamed to be beaten, drew a third line of another colour cutting the two first down their length and leaving no room for any further refinement. Protogenes owned himself beaten and hurried down to the harbour to find his visitor; they agreed to hand down the painting just as it was to posterity, a marvel to all, but especially to artists.' This panel was seen by Pliny (N.H. xxxv. 83) in Rome, where it was much admired, and where it perished by fire. On one picture, the Ialysus, he spent seven years; on
