A 6-foot tall golden spike. It looks a bit like a farming tool, a bit like a scepter, and a bit like a medieval mace. A long solid golden staff ends in a spade-looking tool on one end and in a multi-spiked "business" end. The entire object looks to be made of solid gold; it must weigh near a ton.
The mattock generally is regarded as a symbol of Enlil, and a ceremonial one at that. But this Mattock is not a mere ceremonial symbol, a farming tool made essentially useless by being made of a non-functional, ductile metal. This Mattock is an antenna. A receiving dish. A channel by which data may bee gathered and ... grounded, fed into History A. The data's source is out there, in History B, but is completely alien and encrypted.
