Allegorical sculpture are sculptures of personifications of abstract ideas, as in allegory. Common in the western world, for example, are statues of Lady Justice representing justice, traditionally holding scales and a sword, and the statues of Prudence, representing Truth by holding a mirror and squeezing a serpent.
This approach uses the human form and its posture, gesture, clothing and props to wordlessly convey social values and themes.
It may be seen in funerary art as early as 1580. They were used on Renaissance monuments when patron saints became unacceptable. Particularly popular were the four cardinal virtues and the three Christian virtues, but others such as fame, victory, hope, and time are also represented. The use of allegorical sculpture was fully developed under the École des Beaux-Arts. It is sometimes associated with Victorian art, and is commonly found in works dating from around 1900.
