In my experience, occasionally you discover a piece of art which speaks directly to you, and only poetry gives you the freedom to put words into the 'mouth' of the sculpture. This connection between the two art forms for me goes to the heart of understanding both.
Bernini
Bernini was all about bringing art forms together and breaking boundaries in what is known as bel composto. His church creations are a theatrical installations with a combination of the sculptural, pictorial and architectural. St Teresa is the perfect example. She is in mid transverberation and is sculptural, however the viewer has to step back to see the bel composto, the pictorial effect, essentially a scene from a tableau. Mirrors, lights, and candles all contribute to a theatrical event with viewer as spectator.
