Among the poems of the Greek Anthology is one which purports to be the dedicatory inscription of the Colossus of Rhodes built to celebrate the Rhodians' successful resistance to the siege of their island by Demetrius Poliorcetes in the years 305–304 b.c. It has long been assumed by scholars that this epigram represents the authentic dedicatory inscription carved on the base of the Colossus, which was completed in the 280s and stood for some sixty years before being destroyed by an (...) earthquake that rocked the island of Rhodes in the 220s. There are, however, strong reasons to doubt the epigram's authenticity, some of which come from considerations of the poem itself and others which come from a comparison with a closely related epigram composed by Alcaeus of Messene to celebrate Philip V's military successes during his Aegean campaign of 203–200. Verbal and thematic parallels between the two epigrams make a connection certain. It is the aim of the present study to re-examine the Rhodian epigram and its relation to Anth. Pal. 9.518 in order to propose a new date for the former in the context of Rhodes' defeat of Philip V and the advent of Rome in the affairs of the states ringing the Aegean. (shrink)
