STONEHENGE'S BLUESTONES were rolled rather than dragged from the Preseli Mountains in Wales to their home in Salisbury, according to research by former civil engineering professor Dick Parry.
Parry believes that Neolithic Man wrapped the stones in curved timber, allowing them to be 'to be pushed like a barrel' along a level surface.
Ropes could also be used to pull the stones up an incline and to control descent down slopes - a technique known as par buckling.
He tested the technique in 1998 using a 3t block of concrete that was rolled up an 8degrees incline by 22 people at a fast walking pace.
Parry also claims the technique on a larger scale could have moved Stonehenge's 40t sandstone columns into place.
His theory contradicts the more widely accepted belief that the bluestones were dragged along their 250km journey.
The dragging technique is being used on the £100,000 Lottery funded Millennium Stone project, where a 4t bluestone is re-creating the journey on a sledge. Progress has been slower than expected and the project is on hold until next spring (News last week).
