Skolion

Skolion (from Ancient Greek: σκόλιον) (pl. skolia), also scolion (pl. scolia), were songs sung by invited guests at banquets in ancient Greece. Often extolling the virtues of the gods or heroic men, skolia were improvised to suit the occasion and accompanied by a lyre, which was handed about from singer to singer as the time for each scolion came around. "Capping" verses were exchanged, "by varying, punning, riddling, or cleverly modifying" the previous contribution.
