The task of rendering Greek into English verse is in some respects specially difficult. In the first place, the translator has to deal with a language remarkable for its unity and fluency, qualities which, according to Curtius (_History of Greece_, i. 18), are the result of the "delicately conceived law, according to which all Greek words must end in vowels, or such consonants as give rise to no harshness when followed by others, viz. _n_, _r_, and _s_." Then, again, the translator must struggle with the difficulties arising from the fact that the Greeks regarded condensation in speech as a fine art. Demetrius, or whoever was the author of _De Elocutione_, said: "The first grace of style is that which results from compression." The use of an inflected language of course enabled the Greeks to carry this art to a far higher degree of perfection than can be attained by any modern Europeans. Jebb, for instance, takes twelve words--"Well hath he spoken for one who giveth heed not to fall"--to express a sentiment which Sophocles (_Œd. Tyr._ 616) is able to compress into four--καλῶς ἔλεξεν εὐλαβουμένῳ πεσεῖν. Moreover, albeit under the stress of metrical and linguistic necessity the translator must generally indulge in paraphrase, let him beware lest in doing so he sacrifices that quality in which the Greeks excelled, to wit, simplicity. Nietzsche said, with great truth, "Die Griechen sind, wie das Genie, einfach; deshalb sind sie die unsterblichen Lehrer." Further, the translator has at times so to manipulate his material as to incorporate into his verse epithets and figures of speech of surpassing grace and expressiveness, which do not readily admit of transfiguration into any modern language; such, for instance, as the "much-wooed white-armed Maiden Muse" (πολυμνήστη λευκώλενε παρθένε Μοῦσα) of Empedocles; the "long countless Time" (μακρὸς κἀναρίθμητος Χρόνος), or "babbling Echo" (ἀθυρόστομος Ἀχώ) of Sophocles; the "son, the subject of many prayers" (πολυεύχετος υἱός) and countless other expressions of the Homeric Hymns; the "blooming Love with his pinions of gold" (ὁ δ' ἀμφιθαλής Ἔρος χρυσόπτερος ἡνίας) of Aristophanes; "the eagle, messenger of wide-ruling Zeus, the lord of Thunder" (αἰετός, εὐρυάνακτος ἄγγελος Ζηνὸς ἐρισφαράγου) of Bacchylides; or mighty Pindar's "snowy Etna nursing the whole year's length her frozen snow" (νιφόεσς' Αἴτνα πανετες χιόνος ὀξείας τιθήνα).
