Read the excerpt from the Twelve Tables.
"1. If the plaintiff summons the defendant to court, the
defendant shall go. If the defendant does not go the
plaintiff shall call a witness thereto. Only then the
plaintiff shall seize the defendant.
2. If the defendant attempts evasion or takes flight the
plaintiff shall lay hand on him."
