The Greek word "epigram" in its original meaning is precisely equivalent to the Latin word "inscription"; and it probably came into use in this sense at a very early period of Greek history, anterior even to the invention of prose. Inscriptions at that time, if they went beyond a mere name or set of names, or perhaps the bare statement of a single fact, were necessarily in verse, then the single vehicle of organised expression. Even after prose was in use, an obvious propriety remained in the metrical form as being at once more striking and more easily retained in the memory; while in the case of epitaphs and dedications--for the earlier epigram falls almost entirely under these two heads--religious feeling and a sense of what was due to ancient custom aided the continuance of the old tradition. Herodotus in the course of his History quotes epigrams of both kinds; and with him the word {epigramma} is just on the point of acquiring its literary sense, though this is not yet fixed definitely. In his account of the three ancient tripods dedicated in the temple of Apollo at Thebes,[1] he says of one of them, {o men de eis ton tripodon epigramma ekhei}, and then quotes the single hexameter line engraved upon it. Of the other two he says simply, "they say in hexameter," {legei en exametro tono}. Again, where he describes the funeral monuments at Thermopylae,[2] he uses the words {gramma} and {epigramma} almost in the sense of sepulchural epigrams; {epigegrammai grammata legonta tade}, and a little further on, {epixosmesantes epigrammasi xai stelesi}, "epitaphs and monuments". Among these epitaphs is the celebrated couplet of Simonides[3] which has found a place in all subsequent Anthologies. In the Anthology itself the word does not however in fact occur till a late period. The proem of Meleager to his collection uses the words {soide}, {umnos}, {melisma}, {elegos}, all vaguely, but has no term which corresponds in any degree to our epigram. That of Philippus has one word which describes the epigram by a single quality; he calls his work an {oligostikhia} or collection of poems not exceeding a few lines in length. In an epitaph by Diodorus, a poet of the Augustan age, occurs the phrase {gramma legei},[4] in imitation of the phrase of Herodotus just quoted. This is, no doubt, an intentional archaism; but the word {epigramma} itself does not occur in the collection until the Roman period. Two epigrams on the epigram,[5] one Roman, the other Roman or Byzantine, are preserved, both dealing with the question of the proper length. The former, by Parmenio, merely says that an epigram of many lines is bad--{phemi polustikhien epigrammatos ou xata Mousas einai}. The other is more definite, but unfortunately ambiguous in expression. It runs thus: {Pagxalon eot epigramma to distikhon en de parelthes tous treis rapsodeis xoux epigramma legeis}
