The religious poetry of the Greeks primarily suffered from the influence of the ancient Greek form, which was fatal to original development. The oldest work of this class is the hymn, composed in anapaestic monometers and dimeters, which was handed down in the manuscripts with the _Paedagogus_ of Clement of Alexandria (d. about 215), but was probably not his work. The next piece of this class is the famous "Maidens' Song" in the _Banquet_ of St Methodius (d. about 311), in which many striking violations of the old rules of quantity are already apparent. More faithful to the tradition of the schools was Gregory of Nazianzus. But, owing to the fact that he generally employed antiquated versification and very erudite language, his poems failed to reach the people or to find a place in the services of the church. Just as little could the artificial paraphrase of the Psalms composed by the younger Apollinaris, or the subtle poems of Synesius, become popular. It became more and more patent that, with the archaic metre which was out of keeping with the character of the living language, no genuine poetry suited to the age could possibly be produced. Fortunately, an entirely new form of poetical art was discovered, which conferred upon the Greek people the blessings of an intelligible religious poetry--the rhythmic poem. This no longer depended on difference of quantity in the syllables, which had disappeared from the living language, but on the accent. Yet the transition was not effected by the substitution of accent for the old long syllables; the ancient verse form was entirely abandoned, and in its stead new and variously constructed lines and strophes were formed. In the history of the rhythmic sacred poetry three periods are clearly marked--the preparatory period; that of the hymns; and that of the _Canones_. About the first period we know, unfortunately, comparatively little. It appears that in it church music was in the main confined to the insertion of short songs between the Psalms or other portions of Holy Writ and the acclamations of the congregation. The oldest rhythmic songs date from Gregory of Nazianzus--his "Maidens' Song" and his "Evening Hymn." Church poetry reached its highest expression in the second period, in the grand development of the hymns, i.e. lengthy songs comprising from twenty to thirty similarly constructed strophes, each connected with the next in acrostic fashion. Hymnology, again, attained its highest perfection in the first half of the 6th century with Romanos, who in the great number and excellence of his hymns dominated this species of poetry, as Homer did the Greek epic. From this period dates, moreover, the most famous song of the Greek Church, the so-called _Acathistus_, an anonymous hymn of praise to the Virgin Mary, which has sometimes, but erroneously, been attributed to the patriarch Sergius.
