For their own religious and administrative purposes, the Egyptians compiled lists of kings, sometimes with the exact length of reign.Fragments of such lists survived ('Palermo stone'); none of them is well enough preserved to solve every detail of absolute chronology.After the 'death' of these organic materials the Carbon-14 atoms decay. Therefore it is possible to measure the number of these atoms in organic materials to obtain quantified information on the date of an item.The method has a margin of accuracy of several hundred years and it is therefore not useful to fix dates in historic periods, but very useful for prehistory (in Egypt before 3000 BC).

The tree-ring patterns are matched, and laid down in series, building a continuous timeline of known dates.Bristlecones grow so slowly that a century of tree rings adds less than an inch of girth.The precise, extended chronology of these trees is directly responsible for the accuracy of radiocarbon dating.On the one level, events and individuals are placed in an absolute chronology: the exact years and sometimes even months and days of the events and biographies are known.On the other level, the exact years may not be known, but it is known that one feature is earlier or later in relation to another; this is typically the case on an excavation, where the different archaeological strata allow objects found to be placed in a relative historical framework.
