Róheim pores over a host of primitive narratives surrounding the taboo against sexual relations or baby-making on a holy day. This taboo, and its accompanying narratives, are widespread over the eastern continent; it varies little in form but is applied to different days of the week in various cultures. The days are personified and in some cultures, particularly the Russian, the personification represents the mother. Róheim believes that the taboo and the narrated dangers for breaking it stem from dreams, the content of which is an aggression and defiance toward the mother, followed by retributive punishment.
