<P> The simplest example is the "eye for an eye" principle . In that case, the rule was that punishment must be exactly equal to the crime . Conversely, the twelve tables of Rome merely prescribed particular penalties for particular crimes . The Anglo - Saxon legal code substituted payment of wergild for direct retribution: a particular person's life had a fixed value, derived from his social position; any homicide was compensated by paying the appropriate wergild, regardless of intent . Under the British Common Law, successful plaintiffs were entitled to repayment equal to their loss (in monetary terms). In the modern tort law system, this has been extended to translate non-economic losses into money as well . The meaning of the principle Eye for an Eye is that a person who has been injured by another person returns the offending action to the originator in compensation, or that an authority does so on behalf of the injured person . The exact Latin (lex talionis) to English translation of this phrase is actually "The law of retaliation ." The root principle of this law is to provide equitable retribution . </P> <P> Various ideas regarding the origins of lex talionis exist, but a common one is that it developed as early civilizations grew and a less well - established system for retribution of wrongs, feuds and vendettas, threatened the social fabric . Despite having been replaced with newer modes of legal theory, lex talionis systems served a critical purpose in the development of social systems--the establishment of a body whose purpose was to enact the retaliation and ensure that this was the only punishment . This body was the state in one of its earliest forms . </P> <P> The principle is found in Babylonian Law . If it is surmised that in societies not bound by the rule of law, if a person was hurt, then the injured person (or their relative) would take vengeful retribution on the person who caused the injury . The retribution might be worse than the crime, perhaps even death . Babylonian law put a limit on such actions, restricting the retribution to be no worse than the crime, as long as victim and offender occupied the same status in society . As with blasphemy or lèse - majesté (crimes against a god or a monarch), crimes against one's social betters were punished more severely . </P> <P> Roman law moved toward monetary compensation as a substitute for vengeance . In cases of assault, fixed penalties were set for various injuries, although talio was still permitted if one person broke another's limb . </P>
