If Gordon is right (and I don't doubt that he is) I think we can show that stone rowing is better by far than any other method:

1. Stone rowing is highly efficient in terms of manpower.
2. If extra manpower was available they could have moved stones in procession thereby reducing the overall time.
3. The same method that works on the flat also works on hills with no extra people.
4. Even small escarpments could be tackled by using a log crib.
5. No special preparation of the ground is needed.
6. The materials (logs) are readily available and are recycled throughout the journey.
7. The stones could be rowed on and off boats, barges or rafts for crossing rivers. Tidal waters are ideal for this - dig a dry dock for the vessel, row the stone on, wait for high tide to refloat it.
8. This idea has been though up not by an academic, but by a craftsman, which is exactly what the builders of Stonehenge would have been.

Fragile egos are in for a shock!
