Prairie School architect George Washington Maher worked for Joseph Lyman Silsbee before striking out on his own. During this period Maher developed a system of design that he called the “motif rhythm theory,” in which he created a signature motif to harmonize the interior and exterior of a house through the repetition of decorative details based on local natural forms. He frequently collaborated with Louis J. Millet on his commissions, including the Patrick J. King House (1901), from which this fireplace surround came. This extraordinary object is composed of glass mosaics and features one of Maher’s most prominent motifs, the stylized thistle. It is delicately rendered in shades ranging from pale seafoam green to vibrant greens, blues, and yellows. The fireplace surround is an outstanding example of Millet’s exacting execution of Maher’s designs.
