Prudence (Latin: prudentia, contracted from providentia meaning "seeing ahead, sagacity") is the ability to govern and discipline oneself by the use of reason. It is classically considered to be a virtue - in particular, one of the four cardinal virtues of Ancient Greek philosophy and one of the seven heavenly virtues of Christianity. Prudentia is an allegorical female personification of the virtue, whose attributes are a mirror and snake, and who is frequently depicted as a pair with Justitia, the Roman goddess of Justice.

The word derives from the 14th-century Old French word prudence, which, in turn, derives from the Latin prudentia meaning "foresight, sagacity". It is often associated with wisdom, insight, and knowledge. The virtue of prudence is the ability to judge between virtuous and vicious actions, not only in a general sense, but with regard to appropriate actions at a given time and place. Although prudence does not itself perform outward actions, and is concerned solely with internal discrimination and choice, all other virtues are regulated by it. For example, to distinguish the virtuous mean of courage from the vicious extremes of recklessness (excess) and cowardice (deficiency) is to be prudent.

The Green Man, also known as a foliate head, is a motif in architecture and art, of a face made of, or completely surrounded by, foliage, which normally spreads out from the centre of the face. Apart from a purely decorative function, the Green Man is primarily interpreted as a symbol of rebirth, representing the cycle of new growth that occurs every spring.

The Green Man motif has many variations. Branches or vines may sprout from the mouth, nostrils, or other parts of the face, and these shoots may bear flowers or fruit. Found in many cultures from many ages around the world, the Green Man is often related to natural vegetation deities. Often used as decorative architectural ornaments, where they are a form of mascaron or ornamental head, Green Men are frequently found in architectural sculpture on both secular and ecclesiastical buildings in the Western tradition. In churches in England, the image was used to illustrate a popular sermon describing the mystical origins of the cross of Jesus.
