Attitudes towards sex, marriage, divorce are constantly changing - and at the same time they remain constants of human civilization. In the book “On Marital and Extramarital Life,” journalist Olga Kolobova and archaeologist Valery Ivanov, writing under the common pseudonym Oleg Ivik, summarize their many years of work on these topics. Before us is a fascinating history of marriages, divorces and sexual traditions, which the authors trace over many centuries: from Ancient Egypt to the present. Myths and rituals, complex wedding rules and legal curiosities, marriage rituals of Ancient Rome and Ancient Rus', China and Polynesia - the huge coverage of material in this book is combined with light and cheerful language, which sometimes reminds us of “General History, processed by Satyricon”. Attention! The book contains obscene language.
