That looks more like a very old cutting for the ‘Thames’ through to Port Meadow.

So ‘The Isis’ is only from there onwards until it re-joins at Sandford?

“This is partly due to the old name for the Thames – Tamesis – and because a 14th century monk, Ranulphus Higden, described the river as being a combination of two tributaries, Thama and Ysa. ”

“The Norman conquest of England was the 11th century invasion and occupation of England by an army of Norman, Breton, and French soldiers led by Duke William II of Normandy, later styled as William the Conqueror.”

“D’Oyly positioned his castle to the west side of the town, using the natural protection of a stream of the River Thames on the far side of the castle, now called Castle Mill Stream, and diverting the stream to produce a moat.”

  1. What are your hypotheses about the absence of Roman finds and burials in the alluvial floodplains? Have you considered that at that historical time that the floodplains were at the bottom of a lake or tidewater (do not know their elevations relative to sea levels today)? Do know, I believe, these flood plains must be at near the same elevation (now see the contour lines document this, but I do not edit what I had written in order to demonstrate the fourth dimension–time–involved in my study) unless there was some obstruction preventing water from quickly draining to a lower elevation.

    • “Have you considered that at that historical time that the floodplains were at the bottom of a lake or tidewater”
      But this one has been the same land level for the last 3000+ or years or so, according to the history books (see refs)
