Lacuna

Top

Completely blank area on a painting or painted object or manuscript, resulting from any form of damage. On paintings, the cause may be the gradual decay and loss of adhesion of the paint layers, allowing flakes of paint to become detached. Accidental damage can give rise to larger lacunae.
