Rhyton

A rhyton (plural rhytons or, following the Greek plural, rhyta) is a container from which fluids were intended to be drunk, or else poured in some ceremony such as libation. The English word rhyton originates in the ancient Greek word ῥυτόν (rhŭtón). The conical rhyton form was known in the Aegean region since the Bronze Age; i.e., the 2nd millennium BC. However, it was by no means confined to there. Similar in form to, and perhaps originating from, the drinking horn, it has been widespread over Eurasia since prehistoric times.
