The Golden Bough: A Study in Magic and Religion…
“ Pliny says that “the woods were formerly the temples of the deities, and even now simple country folk dedicate a tall tree to a god with the ritual of the olden time; and we adore sacred groves and the very silence that reigns in them not less devoutly than images that gleam with gold and ivory.” [422] Similarly Seneca writes: “If you come upon a grove of old trees that have shot up above the common height and shut out the sight of the sky by the gloom of their matted boughs, you feel there is a spirit in the place, so lofty is the wood, so lone the spot, so wondrous the thick unbroken shade.” ”
