Size of the Apkallu Artefact
The size of the artefact could be very small like a cuneiform cylinder seal or much larger like the Code of Hammurabi. There is clearly a trade-off between practical build size, cost for production (and reproduction), and a minimum size required to convey the necessary information and knowledge. Another issue is making an artefact that can actually be found. The current thinking is that the artefact will be between 6 - 12 inches in diameter, similar to a football in size.
