This ornate object is the ancient equivalent of the tumbler or the decanter, and was widespread in a vast region, extending east and west of modern-day Iran.
Called a rhyton, it was a vessel to be drunk out of or poured from. Typically, in the shape of an animal’s head or a horn, it had a hole in the front, from which liquid flowed. Those made of silver, gold, or gemstones were luxury wares in royal courts.
The early Greeks coveted them as prestigious Oriental products.
