business of their lives. The possession of a cook, who could answer to the highest expectations of the age, was a prize beyond the reach of all but the most wealthy; for such an expert the sum of four talents had to be paid;[38] he was the prize of the millionaire, and families of more moderate means, if they wished a banquet to be elegantly served, were forced to hire the temporary services of an accomplished artist.[39] The housekeeper,[40] who supervised the resources of the pantry, guided the destinies of the dinner in concert with the _chef_; and each had under him a crowd of assistants of varied names and carefully differentiated functions.[41] The business of the outer world demanded another class of servitors. There were special valets charged with the functions of taking notes and invitations to their masters' friends; there was the valued attendant of quick eye and ready memory, an incredibly rich store-house of names and gossip, an impartial observer of the ways and weaknesses of every class, who could inform his master of the name and attributes of the approaching stranger. There were the lackeys who formed the nucleus of the attendant retinue of clients for the man when he walked abroad, the boys of exquisite form with slender limbs and innocent faces, who were the attendant spirits of the lady as she passed in her litter down the street. The muscles of the stouter slaves now offered facilities for easy journeying that had been before unknown. The Roman official need not sit his horse during the hot hours of the day as he passed through the hamlets of Italy, and the grinning rustic could ask, as he watched the solemn and noiseless transit of the bearers, whether the carefully drawn curtains did not conceal a corpse.[42]
