In 2006 I was doing research for a university study in Australia concerning the construction of the Pyramids at Giza.

Working with real excavated artefacts and ancient documents I was able to discover an ancient type of pulley that is unknown in the modern world until now.

This ancient pulley walks up (or down) steps in a similar way to a three wheel step-trolley and I firmly believe that this is how the ancient Egyptians built their Pyramids.

The Giza Pyramids have steps which I have termed "racks" and there are four "racks" in a square based Pyramid.

The wooden ancient Egyptian Pinion-Pulleys made positive engagements with the Pyramid's stone "racks" carrying a stone block each, rotating as they were being hoisted with ropes.

No ramps were required as the four sides of the Pyramid under construction were progressively used to complete the Pyramid !

This ancient pulley has a mechanical advantage of 2.8, thus is a simple machine and proves the Greek historian, Herodotus to be absolutely correct as he recorded wooden machines made of short wooden planks were used to raise Pyramid blocks of stone.

These planks only needed to be the side length of a Pyramid block which is about one metre and easily carried as Herodotus records.

Well, Herodotus was only writing what Egyptian Priests told him and Egyptian Priests recorded history as part of their duties.

A working model has been made and a book has been published and I wish the World's people to be aware of this work.

The book is dedicated to the Egyptian people to promote "new awareness of their intelligent and innovative glorious historical past".

Four of these lobes surround a Pyramid block and the cross-pegs form a complete rope drum for the hoisting rope.

This is a component of the ancient pulley, that was excavated in AD 1895 by William Matthew Flinders Petrie at Deir el-Bahari for the Egypt Exploration Fund (now Society).
