 His third painting, "The Modern Medea" (1867), portrayed the tragic event from 1856 in which Margaret Garner, a fugitive slave mother, murdered her children rather than see them returned to slavery.The picture is notable for Garner's expression of rage and for including the white slave hunters in the imagery.Noble's last painting, "Price of Blood" (1868), was not based on a specific historical event, but depicted a white slave owner selling his half-white slave son.
