Finally, all the characters of the parade began to walk inside the pool, around its center, mixing the past and the present in a single marching beat of the drums. The confluence of the past and the present is another main theme of the opening ceremony. The music began a crescendo with choruses, when all of a sudden an olive tree was lifted from the center of the pool—symbolizing goddess Athena's preferred gift by the Greeks—land and food—over Poseidon's gift, the horse—a tool of warfare. At the music's climax, all the characters stopped and raised their arms as if worshipping the Tree, which was high above, surrounded also by the fragments of the deconstructed statues who resembled a mount.
