Ancient Greek

Hesiod:

Works and Days, c. 750 BC

First of all, get a house, and a woman and an ox for the plough--a slave woman and not a wife, to follow the oxen as well--and make everything ready at home, so that you may not have to ask of another, and he refuse you, and so, because you are in lack, the season pass by and your work come to nothing.

Strabo:

Geographia circa 550 BCE

And the temple of Aphrodite [at Corinth] was so rich that it owned more than a thousand temples

Slaves---prostitutes---whom both free men and women had dedicated to the goddess. And therefore it was also on account of these temple-prostitutes that the city was crowded with people and grew rich; for instance, the ship captains freely squandered their money, and hence the proverb, "Not for every man is the voyage to Corinth."

Antiphon:

On the Choreutes, c. 430 BCE

So powerful is the compulsion of the law, that even if a man slays one who is his own chattel [i.e., his slave] and who has none to avenge him, his fear of the ordinances of god and of man causes him to purify himself and withhold himself from those places prescribed by law, in the hope that by so doing he will best avoid disaster.

Demosthenes:

Against Timocrates. c. 350 BCE

If, gentlemen of the jury, you will turn over in your minds the question what is the difference between being a slave and being a free man, you will find that the biggest difference is that the body of a slave is made responsible for all his misdeeds, whereas corporal punishment is the last penalty to inflict on a free man.

Aristotle:

The Politics---On Slavery, c. 330 BCE

Let us first speak of master and slave, looking to the needs of practical life and also seeking to attain some better theory of their relation than exists at present. Property is a part of the household, and the art of acquiring property is a part of the art of managing the household; for no man can live well, or indeed live at all, unless he be provided with necessaries. And so, in the arrangement of the family, a slave is a living possession, and property a of such instruments; and the slave is himself an instrument which takes precedence of all other instruments. The master is only the master of the slave; he does not belong to him, whereas the slave is not only the slave of his master, but wholly belongs to him. Hence we see what is the nature and office of a slave; he who is by nature not his own but another's man, is by nature a slave; and he may be said to be another's man who, being a human being, is also a possession. And a possession may be defined as an instrument of action, separable for the professor. But is there any one thus intended by nature to be a slave, and for whom such a condition is expedient and right, or rather is not all slavery a violation of nature? There is no difficulty in answering this question, on grounds both of reason and of fact. For that some should rule and others be ruled is a thing not only necessary, but expedient; from the hour of their birth, some are marked out for subjection, others for rule, again the male.superior and the female inferior; and the one rules, and the other is ruled; this principle, of necessity, extends to all mankind.

Where then there is such a difference as that between soul and body, or between men and animals the lower sort are by nature slaves, and it is better for them as for all inferiors that they should be under the rule of a master. For he who can be, and therefore is, another's and he who participates in rational principle enough to apprehend, but not to have, such a principle, is a slave by nature. Whereas the lower animals cannot even apprehend a principle. They obey their instincts. And indeed the use made of slaves and of tame animals is not very different for both with their bodies' minister
