The Tree Of Life is derived from old Celtic customs, forests of the old world were vast covering whole countries. When a tribe would clear land for a settlement they would always leave one tree in the center, to them this was called in irish "crann bethadh" Tree Of Life. Trees touch all three realms of existence, the heavens with branches, the underworld or spirit world with roots and the mortal world with their trunks.
The metal is Shibuichi 75% copper 25% silver, I won't be casting in this metal again though, the silver absorbed O2 and the copper turns that into oxides. Plus it looks almost the same as tin bronze. I used a clear specialty lacquer for preserving the patina on bronzes and other metals it is exterior grade so it should wear well.
