It is wonderful shot. It has both mystery and a kind of metaphorical meaning about age, life and roots. But you must feel real close to the image, as I did not notice the chain at all. It appears you find it has psychological import for you. So be it. I cannot relate to it in the same way, although I sense what I described earlier. If you look up "Freeman Patterson" the great Canandian photographer who has written many books, he often speaks about how some of his images reflect what he has done and how they are metaphors for his life and work. He explains the signicance of how he came to realize this, almost always, much later, sometimes years later, as the image rises from the subconscious to the concious level. Interesting photo, as are your thoughts on this.
