User:Taxelson/Late Roman gap
Late Roman gap. There are a lot of western European oak chronologies which goes back to about the migration period. There are also a great number of Roman time chronologies from Germany, Netherlands, France and England which forms a consistent complex. But the problem is that very few links - if any - exists between those two complexes! This means that it can be argued that the whole Roman time complex is still floating!
The link seems to be based upon the work of Ernst Hollstein and Berndt Becker only. The Hollstein link, however, is proved to be built on chronologies in which erroneously dated samples have been mixed[1] and according to the Becker chronology (Southern Germany) there are no information available about the quality of the critical Late Roman/Migration period linkage.[2] It is maybe not sure that the Becker chronology did not use the Hollstein chronology as a template. We do not know.
There are also a possible link between the Northern Ireland chronology build down to first century AD and the Roman English complex, but the final, indisputable link between them has not yet been found.[3]
