Euphrosyne of Kersnow. What is that? A memoir? No, it isn't! Leaflets, like faded photographs, which are dear only to those who recognize the faces of long-dead people in vague images - relatives, friends, and in this case, enemies? No, it isn't! What? This is a cave painting: albeit inept drawings inscribed with an inexperienced hand on the walls of caves, but helping people imagine how their distant ancestors hunted mammoths, what weapon they used - in a word, to understand their life and life.
