Ἐργολάβος

The meaning we normally think it right to give to this word, using e)rgola/bos to denote a person who receives a wage for certain services and works with the collaboration of other employees,¹ is not the same the orators apply to e)rgola/bos.² Rather, they use the word in reference to disreputable matters, as Demosthenes [does] in the Letter to the council and the people:³ "for the present situation is far more in need of goodwill and generosity than⁴ turmoil and malice, as⁵ they are using, in excess, the profit-makers to your detriment,⁶ with a view to gaining advantages -- may they be deceived [in such calculations]!"
Also [sc. attested is] e)/rgon, in reference to what is difficult.⁷
Polybius [writes]: "during their siege of Syracuse the Romans had a hard time, since they had not taken into due consideration Archimedes' ability".⁸
