JENTACULUM was, among the Romans, a morning refreshment like our breakfast. It was exceedingly simple, consisting, for the most part, of bread alone; labouring people indeed had something more substantial to enable them to support the fatigues of their employment. What has been here said may be observed of the Jews and Christians also. The Greeks distinguished this morning meal by the several names of agros, akropolisos, or akropolisos, though agros is generally applied to dinner. See EATING and DINNER.
