According to wikipedia:
Momus (/ˈmoʊməs/; Ancient Greek: Μῶμος Momos) in Greek mythology was the personification of satire and mockery, two stories about whom figure among Aesop‘s Fables. 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.
モーモス（古希: Μῶμος, Mōmos、英: Momus 「非難」の意）とは、ギリシア神話に登場する神である。非難や皮肉を擬人化したもの。長母音を省略してモモスとも表記される。ローマ神話ではクエレッラ（ラテン語: Querella, 悲嘆、苦情の意）と同一視される[1]。
