History of the Peloponnesian War

Take the Athenians, for example; most of them think that Hipparchus was tyrant when he was slain by Harmodius and Aristogeiton.[*](514 B.C. On this digression, cf. Hdt. 5.55; 6.123; Aristot. Ath. Pol. 17.)They do not know that it was Hippias, as the eldest of the sons of Peisistratus, who was ruler, and that Hipparchus and Thessalus were merely his brothers; further, that Harmodius and Aristogeiton, suspecting, on that very day and at the very moment of executing their plan, that information had been conveyed to Hippias by one of their fellow-conspirators, held off from him as forewarned, but wishing to do something before they were seized and then take their chances, fell in with Hipparchus, who was marshalling the Panathenaic procession near the sanctuary called Leocorium,[*](In the inner Ceramicus near the temple of Apollo Patrous.) and killed him.
