One was the Puma by Alexander Phimister Proctor - 1916. As a young boy, Proctor loved to hunt and sketch around his hometown of Denver, Colorado. Denver's Civic Plaza in front of the Denver Art Museum has two spectacular bronze sculptures by Proctor, one of a cowboy and his horse, the other of an Indian on his mount.
Paul Manship's Indian and Pronghorn Antelope are spectacular. (1914) He studied the American Academy in Rome where his style was strongly influenced by the Roman, Greek and Egyptian works. Such refined, delicate work. The Indian is modeled after a sculpture of Hercules.
To me the antelope is typical of the time with is Art Noveau influences. One similar to the deer found on the Tourist Pottery of the 1920's from Tonala, Mexico.
If you look closely, you will see the Indian was successful in wounding the antelope with his arrow.
The Mares of Diomedes by John Gutzman de la Mothe Borglum - 1905.Growing up in the west, he portrayed the charging horses as way to capture the true essence of the wild west.
Borglum is best known for his portraits of Washington, Jefferson, Lincoln and Roosevelt that were carved into the side of Mont Rushmore.
The museum in Jackson Hole, Wyoming is one not to be missed!
