Seriation is a standard method of dating in archaeology.

To check on the method before applying it on various historical and paleontological material, Libby chose material of Egyptian archaeology, under the assumption that no other historical material from over 2,000 years ago is so secure as to its absolute dating.

Jørgensen 1992; Two different variants of seriation have been applied: contextual seriation and frequency seriation (Renfrew and Bahn 1996, pp. Whereas contextual seriation is based on the presence or absence of a design style, frequency seriation relies on measuring the proportional abundance or frequency of a design style.

Contextual seriation is often used for reconstructing the chronological sequence of graves as only the presence or absence of a design style or type is important.
