PROMUS. A cellarman and steward; a slave who had charge of the wine and provision stores in a Roman household, and whose duty it was to serve out day by day the necessary quantities of each required for the use of the family; hence the word is often joined with condus, the steward, because the same individual commonly performed both offices. Plaut. Pseud. ii. 2. 14.
