Seal H-166 is held to be of foreign origin. It has two engraved faces. The engraving are pictographic. In my opinion, the seal most probably produced address labels for an intriguing destination.
My hypothesis is that the half of the address label shown on the left is a pictograph of the stepped pyramid of Djoser at Saqqara in Egypt. The key identifying features are firstly, five step levels leading up to a sixth level which bears the Egyptian symbol for sun, and secondly the distinctive perimeter wall with its recessed design, which is presumably meant to convey the impression of fortifications. The orientation of the building on the seal, whereby northwest is conventionally placed at the top, matches that of the Djoser pyramid.
The second half of the address label (not shown here) depicts a bird of prey (a hawk or a falcon) associated with the Egyptian god Horus. It also has two sets of three pyramids shown in profile, one set mirroring the other. Interestingly, the pyramid complex at Giza is said to mirror that of the earlier pyramids at Saqqara. Lastly, on the falcon side of the seal are two symbols for water (again mirrored). Unfortunately, I have no idea what the water symbols signify in this context.
My conclusion is that goods may well have gone from or via Harappa to the temple at Saqqara in Egypt.
