When Hipparchus found his advances repelled by Harmodius he carried out his intention of1
insulting him. There was a young sister of his whom Hipparchus and his friends first invited to come and carry a sacred basket in a procession, and then rejected her, declaring that she had never been invited by them at all because she was unworthy.
At this Harmodius was very angry, and Aristogiton, for his sake, more angry still. They and the other conspirators had already laid their preparations, but were waiting for the festival of the great Panathenaea, when the citizens who took part in the procession assembled in arms; for to do so on any other day would have aroused suspicion. Harmodius and Aristogiton were to begin the attack, and the rest were immediately to join in, and engage with the guards.
The plot had been communicated to a few only, the better to avoid detection; but they hoped that, however few struck the blow, the crowd who would be armed, although not in the secret, would at once rise and assist in the recovery of their own liberties,
