What is "boukris"

Boukris or Boucris was an Aetolian pirate in the 3rd century BC, who raided the Attic countryside and carried off slaves for sale to Crete. The incident is known from an inscription where the Athenians honoured Eumaridas, a Cretan from Kydonia, for releasing the captives. He may be the same person with Boukris son of Daitas from Naupactus, proxenos in Delos. Boukris was also a hieromnemon of the Aetolians in Delphi in the same century.
