John Bostock translation
Or remembrancer; a slave whose duty it was to remind his master of the name of each member of his household; see B. xxix. c. 8. Athenæus, B. vi., speaks of as many as twenty thousand slaves belonging to one household. Demetrius, the freedman of Pompey, mentioned in B. xxxv. c. 58, had a retinue of slaves equal to an army in amount.
