Sicily, says Florus, was full of _ergastula_, and was cultivated by labourers in chains. Eunus and Athenio excited the servile war by breaking up these monstrous prisons and giving liberty to 60,000 slaves. The younger Pompey augmented his army in Spain by the same expedient. If the country-labourers throughout the Roman Empire were so generally in this situation, and if it was difficult or impossible to find separate lodgings for the families of the city-servants, how unfavourable to propagation, as well as to humanity, must the institution of domestic slavery be esteemed.
Constantinople at present requires the same recruits of slaves from all the provinces which Rome did of old, and these provinces are of consequence far from being populous.
Egypt, according to Monsieur Maillet, sends continual colonies of black slaves to the other parts of the Turkish Empire, and receives annually an equal return of white; the one brought from the inland parts of Africa, the other from Mingrella, Circassia, and Tartary.
Our modern convents are no doubt very bad institutions, but there is reason to suspect that anciently every great family in Italy, and probably in other parts of the world, was a species of convent. And though we have reason to detest all those popish institutions as nurseries of the most abject superstition, burdensome to the public and oppressive to the poor prisoners, male as well as female, yet may it be questioned whether they be so destructive to the populousness of a state as is commonly imagined. Were the land which belongs to a convent bestowed on a nobleman, he would spend its revenue on dogs, horses, grooms, footmen, cooks, and housemaids, and his family would not furnish many more citizens than the convent.
The common reason why parents thrust their daughters into nunneries is that they may not be overburdened with too numerous a family; but the ancients had a method almost as innocent and more effectual to that purpose—viz., the exposing their children in the earliest infancy. This practice was very common, and is not mentioned by any author of those times with the horror it deserves, or scarce[53] even with disapprobation. Plutarch—the humane, good-natured Plutarch[54]—recommends it as a virtue in Attalus, King of Pergamus, that he murdered, or, if you will, exposed all his own children in order to leave his crown to the son of his brother, Eumenes, signalising in this manner his gratitude and affection to Eumenes, who had left him his heir preferable to that son. It was Solon, the most celebrated of the sages of Greece, who gave parents permission by law to kill their children.
