A number of structures use metal hooped wooden barrels as props and barrels also show up as treasures. However from what i could find in the game's timeframe barrels were only used in Gaul and (towards the end of the timeline post Gallic Wars) in Roman frontier camps. Barrels in this period seem to have used only wooden hoops; metal hoops seem to first show up in the middle ages and only become truly common after the industrial revolution. My suggestion would be to replace these with the existing pottery and basket props; and possibly create new more accurate barrels for the Gauls in the future.

ok guys, seriously now. Just ignore them. It's not worth it. The devs aren't putting this thread as the arbitor of what ends up happening with something, WFG do their own research and implement things they want to add in the game how they want to add it. They are most certainly not going to listen to a troll on this or the other forum so you don't need to make a heroic stand, just ignore him.

Where's the original? That's the sky, the line coming at an angle is the ecliptic, the yearly apparent path of the Sun, which makes sense for a solar deity. Although many knew the Earth is round, they didn't really represent it as such, nor did they usually think it needed to be held. On the other hand, the sky was often represented as a sphere (since one sees the sky "turning" and showing different constellations through the year), and since it's up, it needed to be held somehow in many myths.
