In terms of antiquarian fame—marbles copied in sketchbooks, paintings, or sculptures from the Renaissance on—the most important work of art in the Gardner collection, and perhaps of its type in America, is the sarcophagus with satyrs and maenads gathering grapes. This large, rectangular coffin of Pentelic marble with one long side and both ends elaborately carved and polished (the second long side left in a less finished state because it stood against a wall in the funerary chamber), was exported from Athens to the area of Rome in the late Severan period, between circa 222 to 235 AD. The occupants of the monument are unknown, since the lid was lost or destroyed some time around 1500. The groups of reveling couples on all sides, combined with the type of lid found on other examples of this Attic imperial sarcophagus, suggest a husband and wife were shown on top, as if reclining at a symposium on an elaborate couch.
