The most notable feature inside the center of the Capitol building is the massive rotunda, with four circular paintings surrounding it. These paintings, painted for the Capitol opening in 1902 by the firm of F. Pedretti's Sons, depict four important archetypes of people of Montana's early history: a Native American (intended to be of Chief Charlo), an explorer and fur trapper (Jim Bridger), a gold miner (Henry Finnis Edgar, one of the discoverers of gold at Alder Gulch), and a cowboy (unidentified, but said to be inspired by the works of C.M. Russell). The Pendretti brothers provided additional commissioned artwork in the Senate and Old Supreme Court Chambers.
