Method of historical dating
This also works with stone tools which are found abundantly at different sites and across long periods of time.Stratigraphic dating is based on the principle of depositional superposition of layers of sediments called strata.Just as in an individual’s life, some birthdates may be so important that the whole culture chooses them as the reference point for its dating system. We are all quite familiar with the BC/AD dating system.
If archaeologists know how pottery styles, glazes, and techniques have changed over time they can date sites based on the ratio of different kinds of pottery.
This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years.
Relative dating includes different techniques, but the most commonly used are soil stratigraphy analysis and typology.
A small number of objects found on excavations contain references to historical figures. Coins are perhaps the most widely known of historically dateable objects.
Most are stamped with the head of the current ruler.
