Data from two sources (the Septuagint and Masoretic Texts) are used to generate exponential functions for expressing the post-Deluge life spans of the Genesis Patriarchs. When the functions are extended into a period of time less questionable than that of the Patriarchs and used to calculate dates and time spans in that period, two of those based on the Septuagint show reasonable agreement with known ualues. These functions are then used to establish a correction factor for the Carbon 14 dating process.
