Wise Trout

I came across a photo of a very battered and crude old Celtic stone carving. In it a fish, which was a salmon or trout, was nose to nose to a man. In Celtic mythology there was a wise salmon living in a dark pool beneath the hazel tree of wisdom, and it lived on the little hazel nuts of knowledge which happened to plunk into the water. This trout is not about to bite his nose, although if you think that it is, it's ok with me.
