There’s an Etruscan word, saeculum, that describes the span of time lived by the oldest person present, sometimes calculated to be about a hundred years. In a looser sense, the word means the expanse of time during which something is in living memory. Every event has its saeculum, and then its sunset when the last person who fought in the Spanish Civil War or the last person who saw the last passenger pigeon is gone. To us, trees seemed to offer another kind of saeculum, a longer time scale and deeper continuity, giving shelter from our ephemerality the way that a tree might offer literal shelter under its boughs.~ Rebecca Solnit from, https://www.themarginalian.org/2022/02/09/rebecca-solnit-trees/
Trees are simply magical. Carl Sagan made a point in the original Cosmos series that everything uses the same basic machinery to read, and write using the same four “letters” of DNA. In a very real sense, trees are us with some different initial inputs. (Setting aside the more ephemeral, yet critical ways where we differ starkly from trees, like degree of consciousness, self-awareness, spirit, soul?) Stand next to an old enough tree and one is invariably transported to a higher level of thinking about being.
