The contrast might also be drawn between two 'dimensions', the historical, and the archaeological, corresponding roughly to the short-term and long-term history envisaged by Fernand Braudel.
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.
Since then, archaeologists have been waiting impatiently for the results of the dating of the fortress. In September 2014, archaeologists from the Danish Castle Centre and Aarhus University announced the discovery of a Viking fortress in a field belonging to Vallø Manor, located west of Køge on the east coast of Sealand.
In the archaeology of part-literate societies, dating may be said to operate on two levels: the absolute exactness found in political history or 'history event-by-event', and the less precise or relative chronology, as found in social and economic history, where life can be seen to change with less precision over time.
Some of the findings listed below certainly fit into this category – from elongated skulls to vampire graves, green slime, and the DNA of Bigfoot.
Here, we feature ten unusual discoveries that took place in 2013.
However, we do not even know the number of kings for all periods, and there is also the possibility that reigns overlapped by coregency or in times of political disunity.
One of the best things about archaeology is uncovering the unexpected.
The carbon-14 dating was performed by the AMS 14C Dating Centre at the Department of Physics and Astronomy at Aarhus University in close collaboration with Accium Bio Sciences' laboratories in Seattle.
