I've an idea about the meaning of the rocking chair. It's just an idea. We can note the chair is just in front the house and between the house in the village , a world of innocence and the forest representing a kind of new world, a world of violence. This position makes me think about two points :
- the rocking chair building with woods is just in front the house to show there are some things coming from the forest into the village ( the ancients)
- the rocking chair seems to look at the forest : it can represent the folk stories that ancients tell to children and perpetuate the legend : there are monsters in this forest . But as I've just say; the rocking chair seems to look at the forest, like it was taking its inspiration from the forest and cultivate the legend.
This is the reason why I think the rocking chair can represent the ancients and their secret.
- The, there is one scene, where you see the house, the rocking chair, Ivy and Lucius and the forest in this order. Ivy and Lucius seem to be just in the middle of two strenghts : the new world and its cruelty, and the village representing the innocence, the easiness, the love.
But Ivy will come in the forest by love, so it can link the village to the rest of the world.
