Anotations

Scope note:

The name applied to a number of Italian marbles, generally containing various hues and patterns of red and brown although other colors such as white and purple are often present. The modern species are coarse and often considered unattractive; the ancient Romans quarried cottanello of superior quality about forty miles from Rome in the Sabine hills, near the town after which the stone is named.
