"It was that glorious hour, with the daylight still glowing everywhere, but the moon already gleaming and the first bats dipping in the green, shimmering air. On the edge of the woods stood dissolving in the last light, bright chestnut trunks against black shadows. A yellow cottage softly radiated the daylight it had absorbed, glowing gently like a topaz. The small paths pink and violet, led through meadows, vineyards and woods..." - Hermann Hesse
