Harmodius and Aristogiton had already their daggers and were getting ready to act, when seeing one of their accomplices talking familiarly with Hippias, who was easy of access to every one, they took fright, and concluded that they were discovered and on the point of being taken; and eager if possible to be revenged first upon the man who had wronged them and for whom they had undertaken all this risk, they rushed, as they were, within the gates, and meeting with hipparchus by the Leocorium recklessly fell upon him at once, infuriated, Aristogiton by love, and Harmodius by insult, and smote him and slew him.
