Again, revolutions occur when great men who are at least of equal excellence are denied honours by those higher in office, as Lysander was by the kings of Sparta; or, when a brave man is excluded from the honours of the state, like Cinadon, who conspired against the Spartans in the reign of Agesilaus; or, again, when some are very poor and others very rich, a state of society which is most often the result of war, as at Lacedaemon in the days of the Messenian War; this is proved from the poem of Tyrtaeus, entitled 'Good Order'; for he speaks of certain citizens who were ruined by the war and wanted to have a redistribution of the land.
