汉默拉比法典，one of the first written codes of law in recorded history， 主旨
就是，以牙还牙，以眼还眼
I am the salvation-bearing shepherd, whose staff is straight, the good
shadow that is spread over my city; on my breast I cherish the inhabitants
of the land of Sumer and Akkad; in my shelter I have let them repose in
peace; in my deep wisdom have I enclosed them.
-Hammurabi’s Code
