Around this time, there was a city in the Middle East. Turkey's Chatalhuyuk, Palestinian Jericho's Tell Es Sultan Tells, Mesopotamia's Eridu, etc.

 The ruins of Tel Abu Shahaline in Eridu have a slight distortion in the outer frame, but the ratio of the golden ratio can be seen. The size of the small room is also the golden ratio, which is the size of the small golden ratio that can be created in the golden ratio of the outside.
