prehistoric trackway from Norfolk to Dorset, Old English Icenhylte (903), of unknown meaning and origin. Name transferred 12c. to the Roman road from Burton on the Water to Templeborough.
For this is one of the most venerable tracks in the land, being the "icknield way," made how long ago Heaven only knows.
Wallingford, where the icknield way crossed the river, was certainly the chief ford below Oxford.
It was used by the Romans and formed part of the famous icknield way, but was made long before their time.
