A drinking horn is the horn of a bovid used as a drinking vessel. 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 as khantsi.
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 (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.
Both in the Greek and the Scythian sphere, vessels of clay or metal shaped like horns were used alongside actual horns from an early time. A Late Archaic (ca. 480 BC) Attic red-figure vase shows Dionysus and a satyr each holding a drinking horn.
During Classical Antiquity, the Thracians and Scythians in particular were known for their custom of drinking from horns (archaeologically, the Iron Age "Thraco-Cimmerian" horizon). Xenophon's account of his dealings with the Thracian leader Seuthes suggests that drinking horns were integral part of the drinking kata ton Thrakion nomon ("after the Thracian fashion"). Diodorus gives an account of a feast prepared by the Getic chief Dromichaites for Lysimachus and selected captives, and the Getians' use of drinking vessels made from horn and wood is explicitly stated.
