Abstract
The decree of Themistocles, discovered by M. H. Jameson and first published by him in 1960 has given rise to an intense debate centring on the question of the decree's authenticity. This debate has focused to an important extent on supposed archaisms or anachronisms in the text. If a word appears to be used in an ‘archaic’ manner, i.e., in this instance, one peculiar to the early fifth century, it may be an indication of the inscription's authenticity. Conversely, a word employed in a manner proper to a later time may be an indication of the decree's actual period of origination. Thus an early and influential commentator, D. M. Lewis, argued for the decree's authenticity asserting: ‘I see no reason to suspect a forgery. There are too many traces of official and archaic language.’
