Featured in the Walter Kelly Gallery in Chicago in 1974, ​Mirrors of Light II consists of a spotlight directed at a diagonal row of mirrors; the resulting refractions form ellipses of varying size and proportion that are projected across the gallery walls. Holt was interested in using light as a medium, while simultaneously examining it as subject matter in its own right. In this single gallery setting, light is a conceptual entity and a physical reality, a practical resource and an aesthetic object. As is the case with the majority of Holt’s oeuvre, ​Mirrors of Light II creates an opportunity for self-examination through the perceptions that arise in the face of her work.  Earlier in 1974 Holt presented Mirrors of Light I in the Bykert Gallery in New York.
