All life is figured by them as a Tree. Igdrasil, the Ash-tree of existence, has its roots deep-down in the kingdoms of Death: its trunk reaches up heaven-high, spreads its boughs over the whole Universe: it is the Tree of Existence. At the foot of it, in the Death-Kingdom, sit the three Fates... watering its roots from the Sacred Well. It's "bough," with their buddings and disleafings, - events, things suffered, things done, catastrophes, - stretch through all lands and times. Is not every leaf of it a biography, every fiber there an act or word? Its boughs are the Histories of Nations. The rustle of it is the noise of Human Existence, onwards from of old. I find no similitude so true as this of a Tree. Beautiful; altogether beautiful and great.
-Thomas Carlyle
