In other words, the poster is wanting to know if the design is original or copied?
I believe the art world has a search engine for things like that....just not sure where you would find it.
Been used for centuries...too vast unless someone would automatically know it. Also, just like in the cookbook/recipe world (just change 2 ingredients/quantity amounts and instruction slightly and it is considered a "new" recipe) just painting it with minute tweaks makes it new and uncopied unless designated in the competition!!!!
Best of luck! You might want to look at Coat of Arms, Griffin (actually used with the name Griffin).
