The Tree of Life is a time-honored idea that dates back to antiquity. It's a symbol that connects death and life, as well as earth and heaven. The roots of the tree grow underground, in the realm of the underworld. After that, the stem bursts through the dirt and ascends to the skies. The upper tree branches wrap, twist, and intertwine like a link to the heavens. As a consequence, the Tree of Existence symbolizes both the continuity and complexities of life. It binds together all areas of existence. Klimt expands on this connection by adopting a flattened style and design elements that encompass the entire region.
