History of the Peloponnesian War

An attempt to seduce him having been made by Hipparchus son of Peisistratus without success, Harmodius denounced him to Aristogeiton. And he, lover-like, deeply resented it, and fearing the power of Hipparchus, lest he might take Harmodius by force, at once plotted, with such influence as he possessed, to overthrow the tyranny.

Meanwhile Hipparchus, having in a second attempt met with no better success in persuading Harmodius, although he had no intention of offering violence, yet laid a plan to insult him in some covert way, as though it were not for this reason.

For he did not generally so exercise his authority as to be oppressive to the mass of the people, but maintained it without giving offence. And indeed the Peisistratidae carried the practice of virtue and discretion to a very high degree, considering that they were tyrants, and although they exacted from the Athenians only five per cent. of their incomes, not only had they embellished their city, but they also carried on its wars and provided sacrifices for the temples.
