Gabriella Polony Mountain's work includes four major themes. The first three themes are clearly recognizable as the Cosmos, Nature, and Figural works with the fourth theme encompassing history, philosophy, and culture. In her life as an artist, Polony Mountain worked with many different medium including mosaics, weavings, sculpture, stained glass, and repousse. Sculpture is a three dimensional branch of the visual arts. In traditional forms of sculpture, the materials used were easily accessible and consisted of stone, metal, wood, ceramics. The process for creating sculpture is as varied as the materials used and include carving, modelling, molded, cast, welded. These days the sculptural form is one with fewer boundaries in terms of material and process.

The white marble sculpture "Mother Protecting Her Child" is a figural representation of the mother and child theme. Polony Mountain uses familiar bold shapes and curvlinear lines to depict a mother embracing and protecting her child.
