This dating method is also known as Archaeological Dating or Historical Chronology. These methods were relied on especially prior to the introduction of scientific methods of dating.

At that time the radioactive disintegration takes over in an uncompensated manner. only half the C-14 will remain after the half-life period.

Clay tablets found in West Asia contain inscriptional evidence with regard to the occurrence of a solar eclipse.
