Red Laws (The).
The civil code of ancient Rome. Juvenal says, Per lege rubras majoram leges (Satires, xiv. 193). The civil laws, being written in vermillion, were called rubrca, and rubrica vetvit means, It is forbidden by the civil laws.
The prætors laws were inscribed in white letters as Quintilian informs us (xii. 3 prtores edicta sua in albo proponebant), and imperial rescripts were written in purple.
