I will try to explain what I mean by metamorphosis. For me no object can be tied down to any sort of reality. A stone may be part of a wall, a piece of sculpture, a lethal weapon, a pebble on a beach or anything else you like.... when you ask me whether a particular in one of my paintings depicts a woman's head, a fish, a vase, a bird, or all four at once, I can't give you a categorical answer, for this 'metamorphosic' confusion is fundamental to the poetry.
