The two volumes, colored black and white respectively, symbolize the opposition between good and evil. The structure creates a striking interplay of solids and voids that allows the sculpture to blend harmoniously with the surrounding landscape.

Over the years, this work has become an integral part of its natural environment, establishing a constant dialogue between contemporary art and the Sicilian territory.

Later, in 264 B.C. at the outbreak of the First Punic War, Halaesa made an alliance with Rome. As a result of this alliance it had the privileges of being exempt from paying tithes, electing senators and magistrates, and governing itself independently. Under Augustus it became a Roman "Municipium." In imperial times it underwent a gradual decline, which reached a climax when it was sacked by the Arabs in the mid-9th century.

In 846 after a violent earthquake, almost the entire population abandoned Halaesa and moved not far away to the place where the Borgo di Tusa stands today. The place name "Tusa" derives from the Arabic tasa with the meaning of "new, recent."

Tusa continued to prosper because of its fertile valley and favorable location for maritime trade.
