native dialects (Alcaeus and Sappho in Aeolic dialect, Anacreon in Ionic); They preferred quite short, metrically simple stanzas or 'strophes' which they re-used in many poems – hence the 'Alcaic' and 'Sapphic' stanzas, named after the two poets who perfected them or possibly invented them. The other six of the canonic nine composed verses for public occasions, performed by choruses and professional singers and typically featuring complex metrical arrangements that were never reproduced in other verses. However, this division into two groups is considered by some modern scholars to be too simplistic and often it is practically impossible to know whether a lyric composition was sung or recited, or whether or not it was accompanied by musical instruments and dance. Even the private reflections of Alcaeus, ostensibly sung at dinner parties, still retain a public function. Critics often seek to understand Alcaeus in comparison with Sappho: The Roman poet, Horace, also compared the two, describing Alcaeus as "more full-throatedly singing" – see Horace's tribute below. Alcaeus himself seems to underscore the difference between his own 'down-to-earth' style and Sappho's more 'celestial' qualities when he describes her almost as a goddess (as cited above), and yet it has been argued that both poets were concerned with a balance between the divine and the profane, each emphasising different elements in that balance. Dionysius of Halicarnassus exhorts us to "Observe in Alcaeus the sublimity, brevity and sweetness coupled with stern power, his splendid figures, and his clearness which was unimpaired by the dialect; and above all mark his manner of expressing his sentiments on public affairs", while Quintilian, after commending Alcaeus for his excellence "in that part of his works where he inveighs against tyrants and contributes to good morals; in his language he is concise, exalted, careful and often like an orator"; goes on to add: "but he descended into wantonness and amours, though better fitted for higher things". Poetic genres The works of Alcaeus are conventionally grouped according to five genres. Political songs: Alcaeus often composed on a political theme, covering the power struggles on Lesbos with the passion and vigour of a partisan, cursing his opponents, rejoicing in their deaths, delivering blood-curdling homilies on the consequences of political inaction and exhorting his comrades to heroic defiance, as in one of his 'ship of state' allegories. Commenting on Alcaeus as a political poet, the scholar Dionysius of Halicarnassus once observed that
