Brent Hardisty is a woodland style painter who works in acrylics on canvas. His spiritual name is Niiwin Binesi translated roughly from Anishnaabemowin means Four Birds. He lived in the city of Toronto in his earlier years and was highly influenced by the graffiti sub-culture.
I envision this to be Sherlock Holmes discovering an ancient obelisk with a mixture of symbols and pictographs and hieroglyphs. On the other side would be Watson. Both are examining this mysterious object with origins they cannot seem to trace - possibly a relic from the ancient past before the end of the ice age of a lost cult.
