Remark :
perpetrator: Aspasia is Milesian. long-term consequence: See Plut. Per. 3.30: "But after the herald who was sent, Anthemocritus, had been put to death through the agency of the Megarians, as it was believed, Charinus proposed a decree against them, to the effect that there be irreconcilable and implacable enmity on the part of Athens towards them, and that whosoever of the Megarians should set foot on the soil of Attica be punished with death; and that the generals, whenever they should take their ancestral oath of office, add to their oath this clause, that they would invade the Megarid twice during each succeeding year; and that Anthemocritus be buried honorably at the Thriasian gates, which are now called the Dipylum."
Notes :
Plutarch mentions that the Megarians seems to be the real murderers (Plut. Per. 3.30).
