Ptolemy was an astronomer and mathematician who probably worked in Alexandria between 127AD and 148AD,
he wrote a number of Astonomical, Mathematical and Astrological books, and his Geographica that describes
the locations of towns, tribes and rivers across the Empire. |
This map is a modern interpretation of the work of Ptolemy's Geographica which shows the approximate
location of the Celtic Tribes after the Roman conquest of 54AD.
Two major forest are shown, Anderida in the south and a second along the
welsh border, the existence and spread of these is derived from the location of Saxon villages
containing 'hurst' which appears to mean forest clearing - see our
Anderida Forest Map.
You will also notice that the map shows the 4 metre high tide levels which influences the coast mostly
in Sussex, Kent, Essex, Norfolk and the Wash. The shape of Britain in todays maps has been massively
influenced by drainage of marshlands and provision of sea defences. The Wash was a tidal basin and the Romney
marsh was predominantly tidal mud flats but other areas especially around Kent, Essex and the Humber have
had major changes. Many thanks to firetree.net for their wonderful website showing sea level effects on
the coastline - link is below.
