The author develops a concept of a specific transgenerational emotional transmission in families of children with two following forms of psychosomatic illnesses: anorexia nervosa and bronchial asthma. With reference to the ideas of Joyce McDougall, Donald Winnicott and Peter Fonagy the author proposes to understand the role of those children in their families as a transitional object for their parents. Children help their parents to regulate their own emotional states. Parents use their children as a transitional object, because they themselves suffered from traumatic emotional experiences in their childhood (Henry Krystal), and could not learn to regulate their affects themselves. The author analyses this intrapsychic mechanism in children in terms of a concept of a prenatal trauma (Suzanne Maiello). The main thesis of this paper is illustrated with a clinical material of a 18-year old girl with anorexia nervosa and bronchial asthma. The mythological figures of Zeus and Hera, the most powerful and dangerous gods of Olymp are chosen as a framework for the dynamics of the analysed family
