The list of kings and the years of their reigns in the antediluvian part of the Sumerian king list has often been likened to the list of biblical partiarchs in Genesis V.{...}As mentioned already, unrealistically huge numbers are used in the king list for the "legendary reigns" of the antediluvial kings, of the kings of the three first dynasties in Kish, and of kings of the first dynasty in Uruk, while more realistic numbers seem to be used for the "historical reigns" of the remaining dynasties. (Similarly, as was shown above, unrealistically large numbers are used in the list of patriarchs in Genesis V.){...}It is difficult to see any mathematical pattern behind the numbers in any one of the antediluvian king lists, just as behind the numbers in the list of patriarchs in Genesis V.
