A Biographical Dictionary of the Celebrated Women of Every Age and Country/Marcia Proba
MARCIA PROBA, Wife of Guithelind, King of the Ancient Britons, before the Birth of our Saviour.
It is said, that having lost her husband very young, she took into her own hand the reins of government, and employed herself in making his people happy, by the wise laws she gave them. These laws were called Leges Marcianœ, or the Marcian Laws. They were translated into Latin by Gildas, and into Saxon by Alfred the Great.
