For finally when the lands had become desolate and barren, of which the masters and the farmers happened to have perished already or leaving their inherited land were being overcome [by] the misfortunes which fell on them because of these [imposts], they do not hesitate to bring [this] upon those who are not yet altogether destroyed."[3]
And this they[4] used to call e)pibolh/ and [the cognate verb] e)piba/llein, as a penalty prescribed for those guardians convicted for wrongdoing towards orphans or for certain others of those who had managed the public funds badly or for those holding others' property and not keeping it in the open. The penalty which the archons prescribe is called e)pibolh/, and the verb is e)piba/llein.[5]
