“The picture on the left is a painting by the Hungarian Tivadar Csontváry Kosztka (1853 – 1919), titled "Old Fisherman". If you mirror the left side, you get a praying old man in a boat on a calm sea. If you do it with the right side, however, the Devil looks at you, behind him a stormy scene.”
I thought the same thing, with the poles looking like chicken feet. This was done for storage to keep vermin out.
It was done for two reasons. 1. Winter cold storage for food. and 2. To keep large animals such as bear and wolves out.
Still done on Alaska homesteads near my home town of Homer.
