Plato, Laws 871e

shall slay him with impunity, or else bind him and hand him over to those magistrates who have judged the case, to be slain. The prosecutor, in a murder-charge, must at once demand bail from the defendant; and the latter shall provide three substantial securities—as approved by the court of the judges in such cases—, who guarantee to produce him at the trial; and if a man be unwilling or unable to provide these sureties, the court must take, bind and keep him, and produce him at the trial of the case.
