Wilisch, _Altkorinthische Thonindustrie_ (1892); Pottier, _Louvre Cat._ ii. p. 417 ff.; Dumont-Pottier, _Céramiques_, i. chaps. xi. and xvi.; Rayet and Collignon, p. 39 ff. For “Proto-Corinthian” pottery see references given in text. As a commercial and artistic centre, no one city during the early archaic period entered into serious rivalry with Corinth, which was at a very remote date in relations with the East, and was one of the first of the Greek states to extend the system of colonisation in the Mediterranean, by the foundation of Corcyra, Syracuse, and other important outposts. The epoch of this supremacy and of its commercial prosperity extends from the eighth to the sixth century B.C., being coincident with the rule of the great tyrants, Periander, Kypselos, etc. In the course of the sixth century, when the Athenian tyranny rose to such a great height under Peisistratos, Corinth, with equal rapidity, sank to a subordinate position, and her artistic supremacy passed to the growing power of Athens. Hence it is fitting that Corinth and its famous potteries should be the subject of our next section. Two causes contributed to the importance of Corinth as a centre of ceramic industry—the excellence of its clay (see p. 205), and its position as a commercial port at the junction of the Peloponnese and Central Greece. Pollux[1010] selects Corinthian clay for commendation, and other writers speak of different varieties of pottery as Corinthian. Hence it is not surprising that large quantities of pottery should have been found here, the local origin of which is established by the inscriptions in the Corinthian alphabet which are frequently painted upon them; and not only that, but similar pottery has been found almost all over the Mediterranean, being more widely distributed than any other fabric except the Athenian B.F. and R.F. vases. The list of sites as given by Wilisch is as follows: Athens, Eleusis, Aegina, Argos, Kleonae, Tiryns, Mycenae, Thebes, and Tanagra in Greece; Euboea (Karystos), Melos, Corfu, Crete, Rhodes,[1011] Samos, and Cyprus among the islands; Hissarlik, Smyrna, Pontus, and the Crimea; Alexandria, Naukratis, and Carthage; Syracuse and Selinus in Sicily, and Sardinia; and many places in Italy, such as Bari, Nola, Capua, Cumae, Beneventum, Cervetri, Vulci, Orvieto, Corneto, and Viterbo. M. Pottier thinks that this wide distribution is due, not to the merit of the vases themselves, which are often of poor style, but to the merchandise which they contained. This might, at any rate, account for the great preponderance of small oil-flasks, a form which took the place of the Mycenaean “false amphora.”
