Modern research into myths and legends have suggested to some, that the Holy Grail idea evolved from the pagan Celtic stories of such magic vessels as the cauldron of plenty. A vessel that supplied endless food to all comers.

However, it is difficult to believe that King Arthur and his followers with a background of 150 years of Christianity, would be attached to a pagan cauldron of plenty myth. But if not, what other reason is there for attaching the Holy Grail stories specifically to Arthur court?

When we ask this question, one answer would be if a vessel or cup was known to have been specifically associated with Arthur up to the 12th.century and the legend regarding it was lost or forgotten due to the Holy Grail taking over Arthur court from it by the end of the century.

To pursue this theme, we recall how Joseph of Arimathea trusted the Grail to Bron and then either Bron or Petrus was told to depart to the west to the vales of Avaron.

However, we should not necessarily assume that Avaron was Avallon, the alleged mythical otherworld to which Arthur was taken after the civil war battle of Camlann. Instead, the vales of Avaron, could just as easily have been, the vales through which a River Avon would run.

In this regard, "The Place-names of Roman Britain", by Rivet and Smith, reveal that the, 'Avon', word generally evolved from the word, 'Abona'. A British word that simply meant, 'river'. Indicating that there are eight Rivers Avon, of which two are in Scotland.

Of those in England, these are all in the south west. Whilst of these, the ones of interest to us are those in the Ravenna Cosmography document that Rivet and Smith in their PLACE-NAMES OF ROMAN BRITAIN reveal as:-
1). A
River Avon that runs from the River Severn through Bristol, Bath and Bradford on Avon and then north towards Chippenham.
2). A
River Avon that runs from the Vale of Pewsey south via Salisbury Plain and Salisbury into the English Channel just east of Bournemouth.

If the vales of Avaron were those through which a River Avon ran and we continue to assume this was actually a river in Britain due to the Joseph of Arimathea connection, then the ideal Avaron or Avon would surely be the one from the Vale of Pewsey in preference to the other.

This is because, just north of the Vale of Pewsey are the 3000 to 4000 year old Avebury Circle and Silbury Hill; the latter, the highest man made mound in Europe. Whilst south of these and close to this particular River Avon, is Stonehenge. A place attached to both Merlin and Arthur by the forerunners of those who compiled the Holy Grail story.

Other than this, within 6 miles of the source of this particular River Avon and on the edge of the Vale of Pewsey, a 2nd. century cup was found in a well at Rudge Coppice, near Froxfield in 1725 and it is the wording on this cup that must intrigue all Arthurians.
