"Fish (Still Life)," Edouard Manet, 1864.
Y'all know Manet. He loved doing still lifes, and seems to have patterned this on works from the Dutch Golden Age. While carefully depicting the preparations for a fish dinner, he's very much confronting the viewer, which people of the time found unorthodox and avant-garde. (Strange to think of this as avant-garde!)
The fish is a mullet; next to it is a red gurnet, a small eel, and a pile of oysters; there's a lemon and a big brass pot, which seems to indicate that they're going to be poached or braised for dinner. Looks good to me...
