While excavating in the ruins of the palace of Sennacherib at Koujounjik in 1880 Mr. Rassam found a small figure of Herakles sculptured in calcareous stone, and inscribed on the front of the plinth with a dedication by a certain Sarapiodoros (Σαραπιόδωρος Ἀρτεμιδώρου—κατ᾿ εὐχήν), and on one side of the plinth with the name of the artist Diogenes (Διογένης ἐποίει). The letters are painted red. The figure is now in the British Museum. Its height is 1 ft. 9 in.A Greek sculptor of the name of Diogenes is known only, so far as I am aware, in the one instance cited by Pliny, in speaking of the sculptural decorations of the Pantheon of Agrippa in Rome, among which he mentions Caryatides ‘in columnis,’ whatever that may mean. These Caryatides by Diogenes the Athenian were much admired. But if Brunn is right, as he appears to be in identifying the statue of this kind in the Vatican Museum as a survivor from the Pantheon, he is evidently right also in concluding that Diogenes had merely made very careful copies from the Caryatides of the Erechtheum. Even a careful copyist was perhaps rare to find in the time of Agrippa. Our Diogenes was no doubt also a copyist, but apparently not a very careful one. For this among other reasons he cannot well be identified with his Athenian namesake. If our Diogenes had been an Athenian he would have said so on the plinth unless he had sculptured his Herakles in Athens where there would have been no occasion to say it.
