The yati structure has raised some interest in the shape and symbolism twelve post down (Jan 9). While the shape may indeed have more than one connection, it is connected to the four directions in Yuchean symbolism. This will be the subject of a subsequent post. The picture below shows the Mayan glyph for Venus being popularized by the furor over Mayan prophecy, and oxhide copper ingot from the Mediterranean. Similar Ingots are known from North American mounds as well which indeed raises some question about ancient trade.
