Oh, I’ve been around, thank you for wondering. Much time spent reading but I also have had little to say here.
I think this little serendipitous find grants the opportunity to say something. I’ve been researching, for quite a while, into sources of pottery and bronze designs in pre-Shang Chinese cultures, as well as Shang and Zhou but also elsewhere in geography and history. The farther we go back in time, the more common and universal basic designs are. There’s a common thread to be noticed. It goes for ancient Middle East and Ancient China and even for some of most ancient extant pottery in the world, The Jomon Culture pottery. I am a believer that ancient pottery designs, as well as some of the engravings in the oldest monuments in the world, like Göbekli Tepe, which is so ancient that even pre-dates pottery, and Çatalhöyük, are some of the earliest expressions of dualism, even if the craftsmen behind them were perhaps unaware of any philosophical implications connected with their designs. The human brain seems to be hard-wired to find symmetry and balance and, where it can’t be found, it tries to recreate it.
I can show lots of examples of found parallels. What I found yesterday, by mere chance, is one parallel I wasn’t expecting to find but, thinking of it, it isn’t that surprising. Some of the Shang ritual bronzes show regular grid patterns, such as this I copied a couple of years ago from ‘Ritual Bronzes of Ancient China by Phillys Ackerman, 1945′.
The patterns are found in two plates, 15 and 22. Pictures below:
