The punishment of treason in ancient Athens

"Archeptolemus son of Hippodamus, the Agrylian, and Antiphon son of Sophilus, the Rhamnusian, being both present in court, are condemned of treason. And this was to be their punishment: that they should be delivered to the eleven executioners, their goods confiscated, the tenth part of them being first consecrated to Athene; their houses to be levelled with the ground, and in the places where they stood this inscription to be engraved on brass, '[The houses] of Archeptolemus and Antiphon, traitors.'

That Archeptolemus and Antiphon should neither of them be buried in Athens, nor anywhere else under that government. And besides all this, that their posterity should be accounted infamous, bastards as well as their lawful descendants; and he too should be held infamous who should adopt any one of their descendants for his son. And that all this should be engraved on a brass tablet, and that tablet should be placed where that stands on which is engraved the decree concerning Phrynichus."
