Petalesharo, (Skidi Pawnees) was a member of the first Native American delegation to be painted by King in Washington, D.C.
He was a romantic figure, having rescued a young woman intended for sacrifice in the Morning Star Ceremony.
During his visit to Washington, he was presented with a silver medal memorializing the act.
The medal was recovered in Howard County, Nebraska in 1883 and is in the collections of the Nebraska Historical Society.
Petalesharo can be seen peering from the balcony in an 1822 painting by Samuel F.B. Morse (1791-1872) entitled "The Old House of Representatives," which is in the collections of the Corcoran Gallery of Art.
He was also a subject in one of King's greatest works, "Young Omaha, War Eagle, Little Missouri, and Pawnees," a group portrait of the 1821 delegation to Washington which is in the Smithsonian American Art Museum.
