In these arts they were regularly taught under masters, and there would likewise appear to have been a set of men who earned their subsistence by initiating slaves in household labours. An example is mentioned at Syracuse of a person[137] who probably had an establishment of his own, where he instructed slaves in the whole round of their domestic duties, such as bread-making, cooking, washing, and so on. In the baker’s business Anaxarchos, an Eudaimonist philosopher, one of the fitting companions of Alexander the Great,[138] introduced an improvement by which modern times may profit,—to preserve his bread pure from the touch, and even from the breath of the slaves who made it, he caused them to knead the dough with gloves on their hands, and to wear a respirator of some gauze-like substance over the mouth.[139] Other individuals, who grudged their domestics a taste of their delicacies, obliged them, while employed at the kneading-trough, to wear a broad collar, like a wheel, which prevented them from bringing their hands to their mouths.[140] This odious practice, however, could not have been general, as it is clear, from an expression in Aristophanes[141] and his scholiast, that slaves employed in making bread used to amuse themselves by eating the dough. This seems to be one of the principal causes of disgust to the rogues in the piece employed in preparing the delicacies with which Trygæos feeds the beetle whereon he is about to mount to the court of Zeus. ----- Footnote 137: Arist.

Footnote 139: This Anaxarchos, upon whom complaisant antiquity bestowed the name of philosopher, was in reality nothing but a libertine courtier, whose manners and tastes are thus described by Clearchos of Soli: Τῶν Εὐδαιμονικῶν καλουμένον Ἀναξάρχω διὰ τὴν τῶν χορηγησάντων ἄγνοιαν περιπεσούσης ἐξουσίας, γυμνὴ μὲν ᾠνοχόει παιδίσκη πρόσηβος, ἡ προκριθεῖσα διαφέρειν ὥρᾳ τῶν ἄλλων· ἀνασύρουσα πρὸς ἀλήθειαν τὴν τῶν οὕτως αὐτῇ χρωμένων ἀκρασίαν· ὁ δὲ σιτοποιὸς χειρίδας ἔχων, καὶ περὶ τῷ στόματι κημὸν, ἔτριβέ τὸ σταῖς, ἵνα μηδὲ ἱδρὼς ἐπιῤῥέῃ, μήτε τοῖς φυράμασιν ὁ τρίβων ἐμπνέοι.
