The Winged lion of Vulci, Louvre, Paris

Nenfro is a volcanic rock, gray tuff or banded trachyte (Brocchi) or leucite phonolite lava (Rosenbusch) with a soft but compact structure,[1] typical of the Viterbo region that the Etruscans used in their sculptures of northern Lazio Cimini hills near Rome, Italy.[2]

One of its features is to take a pinkish tint when drying.[4]
