This recently restored painting in the Vatican, created in 1494 by the Renaissance master Pinturicchio, has a small depiction of naked men with feathered headdresses. This may be the first European depiction of Native Americans. The scene, just above the tomb of Jesus, is too small to be seen in this view of the entire painting but is shown in the photo below.
