Ancient Chinese bronze wine vessel, 5th century BCE, now in the collection of the Minneapolis Institute of Art.
From the wine vessel's description on artsmia.org:
"With its flattened oval form and a brickwork arrangement of rectangular panels decorated with a tight “feather curl” pattern in relief, this wine flask emphasizes the creative approach taken toward surface ornamentation during the late Bronze Age."
