"The Arts of Peace" by James Earle Fraser flank the end of the parkway. "Music and Harvest" on the left consists of a winged horse, Pegasus, between a male figure with a bundle of wheat and a sickle and a woman with a harp. In "Aspiration and Literature" on the right, another Pegasus is flanked by figures holding a book and a bow. The statues, approximately 17 feet tall atop their granite pedestals, are of gilded bronze. The pedestals each bear 36 gilded bronze stars representing the states of the Union at the end of the Civil War. The sculptors were commissioned in l925 and their designs approved in 1933, but the statues were not erected until 1951 after they were cast and gilded by Italy as a gift to the United States. The gilding was restored in 1971.
