Another brief reflection on how Apollon and Artemis work together. The music to day is much interlinked with show and dance. When you have a music show it has dance and, obviously, a dance show has music. Apollon is the patron of music and Artemis of dancing, thus this is another activity in which the twins work together as a single force with two components.
I think that the fact that the gods are twins means much more than most people ever care to investigate.
