Cain and Abel: The Sacrifice and the Murder
Salerno or Amalfi (comes from the Cathedral of Salerno), circa 1384
The Louvre, Paris
God's hand reaching toward Abel's lamb signifies that it is Abel's sacrifice, not Cain's, that is accepted. As usual, Cain's sacrifice is represented as a sheaf of wheat. On the right, Cain strangles his brother to death; many other images have him using a weapon such as an axe or club. On the far right, God curses Cain for what he did.
