Thucydides, who quotes this passage to show the ancient character of the Delian festival, seems to have no doubt of the Homeric authorship of the hymn.
8 The Greek cities, faring ill under Persia, and organized by Onesilaus of Salamis, joined the Ionic revolt in 500 B.C.; 9 but the Phoenician states, Citium and Amathus, remained loyal to Persia; the rising was soon put down; in 480 Cyprus furnished no less than 150 ships to the fleet of Xerxes; 1° and in spite of the repeated attempts of the Delian League to " liberate " the island, it remained subject to Persia during the 5th century."
In his attitude towards the members of the Delian League Pericles likewise maintained a purely Athenian point of view.
The people of Ceos fought on the Greek side at Artemisium and Salamis; they joined the Delian League and also the later Athenian alliance in 377 B.C. They revolted in 3 6 3-3 62, but were reduced again, and the Athenians established a monopoly of the ruddle, or red earth, which was one of the most valuable products of the island.
In the 5th century the three cities were enrolled in the Delian League, and democracies became prevalent.
