Rabbi Aaron Lichtenstein reviews in his book "The Seven Laws of Noah" the work of Philip Biberfeld, and says the following:<ref>[[Aaron Lichtenstein|Lichtenstein, Aaron]]. "The Seven Laws of Noah". New York: The Rabbi Jacob Joseph School Press and Z. Berman Books, 2d ed. 1986</ref>
That we know anything at all about the Hammurabi, Hittite, or Assyrian Codes is due to the preservation of the ancient cuneiform tablets and stones upon which the statutes of these codes were engraved. However, there exists no original text of the Noahide code, and never was the existence of such a text ever reported. The earliest sources to give systematic treatment to Noahide Law are talmudic, and the earliest book of the Halakha which undertakes to deliniate the Seven Laws is the Tosefta, attributed to Hiyya bar Abba, born circa 160.
