Hippopotamus ("William"), Middle Kingdom, Egypt, ca. 1961–1878 B.C., faience, The Metropolitan Museum of Art (accession 17.9.1). Found in the tomb of the steward Senbi at Meir, William was buried with three of his four legs deliberately broken — Egyptians believed hippos were dangerous forces of chaos, so even a protective figure had to be disarmed before entering the afterlife. He's been the Met's informal mascot since 1917 and is today the museum's bestselling plush toy.
