plainly supposes that a slave is always a foreigner. The ancient comic writers represented the slaves as speaking a barbarous language. This was an imitation of nature.
It is well known that Demosthenes, in his nonage, had been defrauded of a large fortune by his tutors, and that afterwards he recovered, by a prosecution of law, the value of his patrimony. His orations on that occasion still remain, and contain a very exact detail of the whole substance left by his father, in money, merchandise, houses, and slaves, together with the value of each particular. Among the rest were 52 slaves, handicraftsmen—viz., 32 sword-cutlers and 20 cabinet-makers,49 all males; not a word of any wives, children, or family, which they {p118} certainly would have had had it been a common custom at Athens to breed from the slaves; and the value of the whole must have depended very much on that circumstance. No female slaves are even so much as mentioned, except some housemaids who belonged to his mother. This argument has great force, if it be not altogether decisive.
