'Commemoration of Abraham's sacrificing of his Son', mid 18th century. An eastern-looking scene, with turbans and a mosque in the distance. According to the Bible, God ordered Abraham to sacrifice his son Isaac as a test of his faith (Genesis, XXII: 1-13). Abraham prepared to carry out the command, proving his belief, but God sent an angel to stay his hand just as he was about to sink the knife into his son's body. Abraham saw a "ram caught in a thicket by his horns", which he sacrificed instead of his son.
