Method of historical dating
It relies upon chronometry, which is also known as timekeeping, and historiography, which examines the writing of history and the use of historical methods.
Radiocarbon dating estimates the age of formerly living things by measuring the proportion of carbon-14 isotope in their carbon content.
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.
Over the 150 years of the discipline of scientific archaeology, researchers have used many different ways to determine how old an artifact or archaeological site is.
Together, the methods contribute to the production of a timescale for events throughout the Quaternary, whether they cover a few million years or a few decades.
