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.

"Mother Lifting Child" is a variation on the mother and child theme. Polony Mountain depicts the mother figure in a standing pose with strong legs and arms. A small child is seated on her left arm. A tether connects the child to the mother signifying perhaps the invisible bond between the two. The facial features of the figures are composed from her usual circular forms and simple shapes highlighting the abstract nature of the bronze sculpture.
