The vernacular literature stands alone, both in form and in contents. We have here remarkable originality of conception and probably also entirely new and genuinely medieval matter. While in the artificial literature prose is pre-eminent, in the vernacular literature, poetry, both in quantity and quality, takes the first place, as was also the case among the Latin nations, where the vulgar tongue first invaded the field of poetry and only later that of prose. Though a few preliminary attempts were made (proverbs, acclamations addressed by the people to the emperor, &c.), the Greek vernacular was employed for larger works only from the 12th century onwards; at first in poems, of which the major portion were cast in "political" verse, but some in the trochaic eight-syllabled line. Towards the close of the 15th century rhyme came into use. The subjects treated in this vernacular poetry are exceedingly diverse. In the capital city a mixture of the learned and the popular language was first used in poems of admonition, praise and supplication. In this oldest class of "vulgar" works must be reckoned the _Spaneas_, an admonitory poem in imitation of the letter of Pseudo-Isocrates addressed to Demonicus; a supplicatory poem composed in prison by the chronicler Michael Glycas, and several begging poems of Theodorus Prodromus (Ptochoprodromos). In the succeeding period erotic poems are met with, such as the Rhodian love songs preserved in a MS. in the British Museum (ed. W. Wagner, Leipzig, 1879), fairy-tale like romances such as the _Story of Ptocholeon_, oracles, prayers, extracts from Holy Writ, lives of saints, &c. Great epic poems, in which antique subjects are treated, such as the legends of Troy and of Alexander, form a separate group. To these may be added romances in verse after the manner of the works written in the artificial classical language, e.g. _Callimachus and Chrysorrhoe_, _Belthandrus and Chrysantza_, _Lybistrus and Rhodamne_, also romances in verse after the Western pattern, such as _Phlorius_ and _Platziaphlora_ (the old French story of _Flore et Blanchefleur_). Curious are also sundry legends connected with animals and plants, such as an adaptation of the famous medieval animal fables of the _Physiologus_, a history of quadrupeds, and a book of birds, both written with a satirical intention, and, lastly, a rendering of the story of Reynard the Fox. Of quite peculiar originality also are several legendary and historical poems, in which famous heroes and historical events are celebrated. There are, for instance, poems on the fall of Constantinople, the taking of Athens and Trebizond, the devastating campaign of Timur, the plague in Rhodes in 1498, &c. In respect of importance and antiquity the great heroic epic of Digenis Akritas stands pre-eminent. "Vulgar" prose works.
