Instances are very frequent in ancient history of cities besieged whose inhabitants, rather than open their gates, murdered their wives and children, and rushed themselves on a voluntary death, sweetened perhaps with a little prospect of revenge upon the enemy. Greeks as well as barbarians have been often wrought up to this degree of fury. And the same determined spirit and cruelty must, in many other instances less remarkable, have been extremely destructive to human society in those petty commonwealths which lived in a close neighbourhood, and were engaged in perpetual wars and contentions. Sometimes the wars in Greece, says Plutarch, were carried on entirely by inroads and robberies and piracies. Such a method of war must be more destructive in small states than the bloodiest battles and sieges. By the laws of the twelve tables, possession for two years formed a prescription for land; one year for movables;​[60] an indication that there was not in Italy during that period much more order, tranquillity, and settled police than there is at present among the Tartars. The only cartel I remember in ancient history is that between Demetrius Poliorcetes and the Rhodians, when it was agreed that a free citizen should be restored for 1000 drachmas, a slave bearing arms for 500. But, secondly, it appears that ancient manners were more unfavourable than the modern, not only in times of war but also in those of peace; and that too in every respect, except the love of civil liberty and equality, which is, I own, of considerable importance. To exclude faction from a free government is very difficult, if not altogether impracticable; but such inveterate rage between the factions and such bloody maxims are found, in modern times, amongst religious parties alone, where bigoted priests are the accusers, judges, and executioners. In ancient history we may always observe, where one party prevailed, whether the nobles or people (for I can observe no difference in this respect​[61]), that they immediately butchered all of the opposite party who fell into their hands, and banished such as had been so fortunate as to escape their fury. No form of process, no law, no trial, no pardon. A fourth, a third, perhaps near a half of the city were slaughtered or expelled every revolution; and the exiles always joined foreign enemies and did all the mischief possible to their fellow-citizens, till fortune put it in their power to take full revenge by a new revolution. And as these were very frequent in such violent governments, the disorder, diffidence, jealousy, enmity which must prevail are not easy for us to imagine in this age of the world.
