what are the qualities of the greek literature?

Answer 1

Your question is not clear what do you mean by Greek literature , it means Ancient greek literature or Modern greek literature.

If you mean Ancient Greek literature then the answer is
Classical Greek or Ancient greek literature.
Ancient Greek literature refers to literature written in Ancient Greek from the oldest surviving written works in the Greek language until the 4th century and the rise of the Byzantine Empire. At the beginning of Greek literature stand the two monumental works of Homer, the Iliad and the Odyssey. The other great poet of the preclassical period was Hesiod. His three surviving works are Works and Days and Theogony.

The two major lyrical poets were Sappho and Pindar. The Greeks also invented drama and produced masterpieces that are still reckoned as drama's crowning achievement. Of the hundreds of tragedies written and performed during the classical age, only a limited number of plays by three authors have survived: Aeschylus, Sophocles, and Euripides.

Modern Greek literature
Modern Greek literature refers to literature written in the Greek language from the 11th century, with texts written in a language that is more familiar to the ears of Greeks today than is the language of the early Byzantine literati, the compilers of the New Testament, or, of course, the classical authors of the fifth and fourth centuries BC.
