Inscription.
This two-part sculpture recognizes the significant contributions of Pittsburgh and to American labor history by a symbolic representation of labor's role in our nation's development. The human figures populating the facades are engaged in this activity, while the palm trees and marine life are reminders of the delicate balance between civilization and nature.

On the upper level, "Piazza Lavoro" suggests the heights to which civilization may be elevated. On the lower level, "Mythic Source" refers to life's aquatic origins and the sustaining powers of the water.
