Ramps

'...a system of ramps must have been used to drag the millions of blocks into their positions in the various pyramids.'

Most archaeologists agree that a system of ramps must have been used to drag the millions of blocks into their positions in the various pyramids. No such ramps have actually survived at the Great Pyramid itself, but enough traces can be seen around some of the other Old Kingdom pyramids to suggest that at least five different systems of ramp might have been used.

The most straightforward method would have been the so-called linear ramp, probably used in the Third-Dynasty pyramid of Sekhemkhet, at Saqqara. Such ramps, however, were probably rarely used, because they would have had to be very wide. An alternative would have been the 'staircase ramp', a steep and narrow set of steps leading up one face of the pyramid, traces of which have been found at the Sinki, Meidum, Giza, Abu Ghurob and Lisht pyramids.

In the case of the 'spiral ramp' (perhaps described in the Nineteenth-Dynasty Papyrus Anastasi I), the question arises of what it would have rested on, and how corrective calculations and checks could have been made from the corners if most of the pyramid was continually covered up. The 'reversing ramp', a zigzag course up one face of a pyramid, would probably have been most effective for the construction of step pyramids, although, frustratingly, there are no signs of its use on the step pyramids at Saqqara, Sinki and Meidum.

'...the causeways stretching from pyramid to valley temple might originally have served as builders' ramps from quay to construction site...'

Traces of 'interior ramps' have survived inside the remains of the pyramids of Sahura, Nyuserra and Neferirkara, at Abusir, and of Pepi II, at Saqqara, but some kind of exterior ramp would still have been needed after the interior was filled in. The terraced nature of the pyramid core would often have made it more convenient to use a series of much smaller ramps built along the sides of the pyramid from step to step. The remains of these would no doubt have been lost when the outer casing was applied. It is also possible that the causeways stretching from pyramid to valley temple might originally have served as builders' ramps from quay to construction site (the quay being connected with the Nile by canal).
