Horn-Shaped Drinking Cup - Public domain museum image. A white object with a curved shape on a gray surface

Drinking horns are known from Classical Antiquity, especially the Balkans, and remained in use for ceremonial purposes throughout the Middle Ages and the Early Modern period in some parts of Europe, notably in Germanic Europe, and in the Caucasus. Drinking horns remain an important accessory in the culture of ritual toasting in Georgia in particular, where they are known by the local name of kantsi. Drinking vessels made from glass, wood, ceramics or metal styled in the shape of drinking horns are also known from antiquity. The ancient Greek term for a drinking horn was simply keras (plural kerata, "horn"). To be distinguished from the drinking-horn proper is the rhyton (plural rhyta), a drinking-vessel made in the shape of a horn with an outlet at the pointed end.
