This state was home to a naïve artist who depicted a prophecy from the Book of Isaiah in over 60 paintings of a “Peaceable Kingdom.” Violet Oakley and Cecilia Beaux studied at this state's first academy and museum, whose collection is revealed by the drawing of a curtain in a self-portrait titled The Artist in His Museum. Natives from this state who used clay and bear grease to mix color taught a history painter who depicted some of them looking on as a (*) roll of cloth is unfurled by the entourage of a religious leader during the signing of a treaty. The sculptor of Nymph and Bittern, William Rush, co-founded this state’s Academy of Fine Arts, (10[1])which taught a resident of this state who painted The Swimming Hole. For 10 points, name this (10[1])state where artist Benjamin West was born to a family of Quakers. ■END■ (10[1]0[1])
