History of the Peloponnesian War

For the fact of Aristogeiton and Harmodius was undertaken upon an accident of love, which unfolding at large, I shall make appear that neither any other, nor the Athenians themselves, report any certainty either of their own tyrants or of the fact.

For the old Peisistratus dying in the tyranny, not Hipparchus, as the most thing, but Hippias, who was his eldest son, succeeded in the government. Now Harmodius, a man in the flower of his youth, of great beauty, was in the power of one Aristogeiton, a citizen of a middle condition that was his lover.

This Harmodius, having been solicited by Hipparchus, the son of Peisistratus, and not yielding, discovered the same unto Aristogeiton. He apprehending it (as lovers use) with a great deal of anguish and fearing the power of Hipparchus, lest he should take him away by force, fell presently, as much as his condition would permit, to a contriving how to pull down the tyranny.
