MUSES MELPOMENE, ERATO, AND POLYMNIE ARE AMUSING
"Melpomene, Erato and Polymnie", 1652 Eustache Le Sueur (1616-1655) Louvre Museum, Paris, France
Melpomene does not represent here tragedy as per Virgil; instead, it stands for song and music as per Horace. Erato represents love and poetry and plays the viola. Polymnie represents lyric poetry and holds a book.
