CYATHUS, cyathos (from the verb cyathos, to pour out), was a common measure among the Greeks and Romans, both of the liquid and dry kind. It was equal to an ounce, or the twelfth part of a pint. The cyathus was made with a handle like our punch-ladle. The Roman toppers used to drink as many cyathi as there were muses, i. e. nine; also as many as there were letters in the patron's name. Thus, they had modes of drinking similar to the modern health-drinking or toasting. The cyathus of the Greeks weighed 10 drachms; but Galen says that a cyathus contains 12 drachms of oil, 13 drachms and one scruple of wine, water, or vinegar, and 18 drachms of honey; and he adds that among the Veterinarii the cyathus contained two ounces.
