On the wall over the Speaker's Chair at the head of the chamber is a magnificent version of Michigan's coat-of-arms, rendered in cast plaster, glaze, paint, and gold leaf. On the left is an elk and on the right a moose, flanking our national symbol, the eagle. Above the eagle are the Latin words of our national motto, "EPluribus Unum," meaning "From many, one." A shield bears the Latin word, "Tuebor," meaning, "I will defend." Below is a small figure standing on a peninsula backed by the rising rays of the sun. All is supported by banners bearing the Latin words of Michigan's motto, "Si quaeris peninsulam amoenam, circumspice," meaning, "If you seek a pleasant peninsula, look around you." At the time the motto was written, the Upper Peninsula was not part of Michigan.
The Great Seal of the State of Michigan, from which the coat-of-arms is taken, was designed in 1835 by General Lewis Cass, former governor of Michigan Territory. He based the design on the seal of the Hudson Bay Fur Trading Company.
