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. Weaving is a technique used to make textiles by interlacing thread. This technique can be accomplished with the use of an instrument called a loom, or by hand in various methods such as knitting, crocheting, felting, braiding, or plaiting. Polony-Mountain used a combination of loom and hand weaving techniques. And like her weaving techniques, Polony-Mountain used a combination of acrylic, cotton, and wool yarns to create her vibrant textiles. "Mountain Precipice" leads the viewer between a winding, yet brightly colored crevice to the base of a blue mountain. The yellow sun shines bold and bright against a sky of pastel hues in pink, lavender, blue, and green. A subdued juxaposition from the vivid yellow, blue, green, orange, and red that comprise the landscape that encompasses the brown and russet pathway. Polony Mountian's signature use of repeat shapes is represented in this piece with ovals, circles, and curvilinear forms. A lovely example of the artist's unique ability to leap from one kind of material and form to another and to shift thematic content to create art.
