‘Time,’ said Nimue, ‘has neither a beginning nor an end. Time is like the serpent Ouroboros, which bites its own tail with its teeth. Eternity is hidden in every moment. And eternity consists of the moments that create it. Eternity is an archipelago of moments. You may sail through that archipelago, although navigation is very difficult, and it is dangerous to get lost. It’s good to have a lighthouse whose light can guide you. It’s good to be able to hear someone calling among the fog . . .’
