Trees resemble humans. Like us, they have arms (branches), feet (roots), a body (the trunk), blood which nourishes them (the sap), hair which they lose (their leaves). But some of them resemble us even more. These are the anthropomorphic or zoomorphic trees in which we actually seem to see human or animal forms, as if they were imprisoned within the tree form. And when we do so, the tree, so familiar, becomes at once something extraordinary, strange, improbable and venerated – for it is the proof that mysterious forces can imprison, within wood, living creatures.
