Closely tied to architecture since it was used primarily to decorate the exteriors of cathedrals and other religious buildings. The earliest Gothic sculptures were stone figures of saints and the Holy Family used to decorate the doorways, or portals, of cathedrals. Early Gothic masons also began to observe such natural forms as plants more closely, as is evident in the realistically carven clusters of leaves that adorn the capitals of columns. Monumental sculptures assumed an increasingly prominent role during the High and late Gothic periods and were placed in large numbers on the facades of cathedrals, often in their own niches. In the 14th century, Gothic sculpture became more refined and elegant and acquired a mannered daintiness in its elaborate and finicky drapery.
