“Artists and writers have always had a rather exaggerated idea about what goes on at a witches’ sabbat. This comes from spending too much time in small rooms with the curtains drawn, instead of getting out in the healthy fresh air. For example, there’s the dancing around naked. In the average temperate climate there are very few nights when anyone would dance around at midnight with no clothes on, quite apart from the question of stones, thistles, and sudden hedgehogs.”
