Much akin to this wood framing is the panelling of the brickwork which is seen in the earliest examples in Egypt, and is identical with the panelling of walls in early Babylonia, one of the indications of a common civilisation of the two great valleys. This panelling does not seem to have lasted beyond the Old Kingdom; there was no trace of it found at Kahun or Gurob, in the buildings of the XIIth and XVIIIth dynasties, nor does it appear in any drawings or imitations of buildings.
