The poets of the period of Cretan literature (15th-17th centuries) used the spoken Cretan dialect. The tendency to purge the language of foreign elements was above all represented by Chortatsis, Kornaros and the anonymous poets of Voskopoula and the "Sacrifice of Abraham", whose works highlight the expressive power of the dialect. As dictated by the pseudo-Aristotelian theory of decorum, the heroes of the works use a vocabulary analogous to their social and educational background. It was thanks to this convention that the Cretan comedies were written in a language that was an amalgam of Italicisms, Latinisms and the local dialect, thereby approximating to the actual language of the middle class of the Cretan towns. The time span separating Antonios Achelis, author of the Siege of Malta (1570), and Chortatsis and Kornaros is too short to allow for the formation, from scratch, of the Cretan dialect that are seen in the texts of the latter two. The only explanation, therefore, is that the poets at the end of the sixteenth century were consciously employing a particular linguistic preference – they were aiming at a pure style of language for their literature and, via that language, a separate identity for the Greek literary production of their homeland.
