Momus (/ˈmoʊməs/; Greek: Μῶμος Momos) was in Greek mythology the personification of satire and mockery.
As a sharp-tongued spirit of unfair criticism, Momus was eventually expelled from the company of the gods on Mount Olympus.
During the Renaissance, several literary works used him as a mouthpiece for their criticism of tyranny, while others later made him a critic of contemporary society. Onstage he finally became the figure of harmless fun.
In the 17th century English writers introduced the figure of Momus in a gentler spirit of fun and elsewhere in Europe, Momus was becoming softened into a figure of light-hearted and sentimental comedy, the equivalent of Harlequin in the French and Italian Commedia dell'arte.
