Cart ruts served defensive purpose

I have a new theory on the prehistoric cart ruts or tracks. These parallel ruts have, to date puzzled many people as to their purpose during prehistoric times. Times when mechanics must have been basic, such as gravity, leverage, animal and manpower. I am, therefore, putting forward my theory.

I believe that these were used for defensive purposes. The defenders would load wooden trucks with stones at the top of a hill, push them down the slope and the cart spills the stones on to the invaders trying to climb the slope. Successive carts would make defence more effective.

Carts could have been pushed in different directions simultaneously, such as at so-called 'Clapham Junction'. Those ruts ending at the edge of a cliff would attack climbers up the cliff or a boat.

I shall be featuring this subject in a book that I am about to publish on the early history of Malta. At the same time I wish to state that the handling of megaliths (the large stones of the prehistoric temples) must have been with the help of animals, probably bulls, pulling these large stones, and not a number of men as is normally thought.

Animals must also have been used during the construction of the Pyramids of Egypt. Many people still think they were just men moving these hefty stones and that is still remains a mistry for some people.

Although these solutions may sound simple, they may be effective.
