Cotyla
- The cotylae are also features on the proximal end of the radius and of the ulna in birds.
In classical antiquity, the cotyla or cotyle (Script error: No such module "params".) was a measure of capacity among the Greeks and Romans: by the latter it was also called Template:Wikt-lang; by the former, Script error: No such module "Lang". and Script error: No such module "Lang". or Script error: No such module "Lang".. It was the half of the sextarius[1] or Script error: No such module "Lang"., and contained six cyathi, or nearly half a pint English.[2]
This measure was used by physicians with a graduated scale marked on it for measuring out given weights of fluids, especially oil. A vessel or horn, of a cubic or cylindrical shape, and of the capacity of a cotyla, was divided into twelve equal parts by lines cut on its side. The whole vessel was called litra, and each of the parts an ounce (Script error: No such module "Lang".). This measure held nine ounces (by weight) of oil, so that the ratio of the weight of the oil to the number of ounces it occupied in the measure would be 9:12 or 3:4.[2]
Nicolas Chorier (1612–1692) observes that the cotyla was used as a dry measure as well as a liquid one, from the authority of Thucydides, who in one place mentions two cotylae of wine, and in another two cotylae of bread.[3]
The name is also given to a type of ancient Greek vase broadly similar in shape to a skyphos but more closely resembling a kantharos.
