I. e. paleness or pale fear, or a personification of it, was together with Pavor, i. e. Fear, a companion of Mars among the Romans. Their worship is said to have been vowed and instituted by the warlike king Tullus Hostilius, either on account of a plague, or at the moment when in battle he saw the Alban Mettus desert to the enemies. The Salii, Pallorii, and Pavorii were instituted at the same time. (Liv. i. 27 ; August. De Civ. Dei, iv. 23.)
