Many of the best poets of modern Greece have written in the vernacular, which is best adapted for the natural and spontaneous expression of the feelings. Dionysios Solomos (1798-1857), the greatest of them all, employed the dialect of the Ionian Islands. Of his lyrics, which are full of poetic fire and inspiration, the most celebrated is his "Ode to Liberty." Other poets, of what may be described as the Ionic school, such as Andreas Kalvos (1796-1869), Julius Typaldos (1814-1883), John Zampelios (1787-1856), and Gerasimos Markoras (b. 1826), followed his example in using the Heptanesian dialect. On the other hand, Georgios Terzetes (1806-1874), Aristotle Valaorites (1824-1879) and Gerasimos Mavrogiannes, though natives of the Ionian Islands, adopted in their lyrics the language of the Klephtic ballads--in other words, the vernacular of the Pindus range and the mountainous district of Epirus. This dialect had at least the advantage of being generally current throughout the mainland, while it derived distinction from the heroic exploits of the champions of Greek liberty. The poems of Valaorites, which are characterized by vivid imagination and grace of style, have made a deep impression on the nation. Other poets who largely employed the Epirotic dialect and drew their inspiration from the Klephtic songs were John Vilaras (1771-1823), George Zalokostas (1805-1857) in his lyric pieces, and Theodore Aphentoules, a Cretan (d. 1893). With the poems of this group may be classed those of Demetrius Bikelas (b. 1835). The popular language has been generally adopted by the younger generation of poets, among whom may be mentioned Aristomenes Probelegios (b. 1850), George Bizyenos (1853-1896), George Drosines, Kostes Palamas (b. 1859), John Polemes, Argyres Ephthaliotes, and Jacob Polylas (d. 1896).
