On my visit to the Brooklyn Museum Summer 2015:
“Edward Hicks (April 4, 1780 – August 23, 1849) was an American folk painter and distinguished religious minister of the Society of Friends (aka “Quakers”). He became a Quaker icon because of his paintings.
“Although it is not considered a religious image, Hicks’ Peaceable Kingdom exemplifies Quaker ideals. Hicks painted 62 versions of this composition. The animals and children are taken from Isaiah 11:6–8 (also echoed in Isaiah 65:25), including the lion eating straw with the ox. Hicks used his paintings as a way to define his central interest, which was the quest for a redeemed soul. This theme was also from one of his theological beliefs. “(Source: Wikipedia)
