First Unitarian Church of Dallas

Medellín produced numerous fused glass windows (see Moody Performance Hall and Dallas Love Field), but his passion for glass was not limited to two dimensions. He was also interested in how glass could be utilized in three-dimensional sculptures. In works like "The Sun and the Firmament," commissioned by Florence and Donald Lewis in 1966 for First Unitarian Church of Dallas, the artist used slump molds (a concave plaster mold) to create the three primary forms; he then attached a metal framework to set the glass off from the wall and take advantage of its luminous qualities. As the sunlight hits it, the blue and amber glass glows and brings the work to life. Although its exact subject remains unclear, the artist noted that the work alludes to the mythology of the Nahua people of Mexico.
