Thalia (//; Ancient Greek: Θάλεια, Θαλία; "the joyous, the flourishing", from Ancient Greek: θάλλειν, thállein; "to flourish, to be verdant"), also spelled Thaleia, was the Muse who presided over comedy and idyllic poetry. In this context her name means "flourishing", because the praises in her songs flourish through time. She was the daughter of Zeus and Mnemosyne, the eighth-born of the nine Muses.
She was portrayed as a young woman with a joyous air, crowned with ivy, wearing boots and holding a comic mask in her hand. Many of her statues also hold a bugle and a trumpet (both used to support the actors' voices in ancient comedy), or occasionally a shepherd’s staff or a wreath of ivy.
