Several possibilities come to mind that are supported by the evidence...
- - The 4th Dynasty workers didn't understand, or care about, such precision. Of course, the adjacent faces seem precise enough to seal with a bit of mortar fairly well, so it's clear they could have evened the top surface if they wanted to. So I think this possibility isn't very likely, especially in lieu of the following item...
- The different heights were a deliberate means to provide an irregular surface to secure the overlying patio. However, if this were true, we might still expect the other dimensions to be similar (N/S length and E/W thickness), but that's not what we find. Rather, each block appears to have its own unique dimension along each axis. There appears to be a large spectrum of sizes among the cover beams and no consistent measurements apply. There doesn't seem to be any representation of an Egyptian cubit (except perhaps for a very occasional coincidence). In fact, the beams vary in thickness along their length. So acting as an anchor to secure the overlying patio seems less likely to be the primary motive for such irregular shapes.
- The blocks were scavenged from other pre-existing buildings and repurposed by the OK workers. The ledges of both southern boat pits (G1) are crude and vary in width not only when comparing the northern ledge with the southern ledge, but also at various points along the same ledge. This is an adaption scenario and I consider it to be a more likely possibility.
- The blocks were originally installed before the OK and before those pits were used to house boats, and so we don't know what their original purpose was. Obviously another adapation scenario and a more likely possibility.
How can any of us ever know, when all we can do is think?
