Summary description Starting from the sociological theory according to which childhood is a social construction, that is, the identity and status of children, and childhood as a separate phase of life were created by society and its opinions and attitudes towards it, the first chapter (Building Byzantine childhood) focuses in the introductory part on the life stages of Byzantine children from birth to the beginning of adolescence and examines the stages divided with its specific terminology and characteristics. The chapter will also address the issues of birth, baptism, breastfeeding, and weaning as important transition markers in the lives of Byzantine children, as depicted in hagiographic sources. I will examine the circumstances of birth, the time and place of baptism, the names chosen and their meaning in the Byzantine mentality, the importance of godparents in children's lives and family relationships. The issues of breastfeeding and weaning will be explored in terms of emotional bonds between children and mothers, placing emphasis on the importance attributed by hagiographers to this practice in children's development. The second chapter (Physiognomy and Personality) focuses on the description of Byzantine children in narrative sources. My aim is to examine how Byzantine authors represented the physical and psychological characteristics of children in hagiographies. Although in most of the hagiographies examined the authors do not provide a specific physical description of the children, it is important to find out what characteristics the authors took into consideration when talking about the children. What a child... in the center of the paper... emotional bonds between children and parents, children and siblings and relatives. How did Byzantine parents express their affection towards their offspring and, consequently, how did their children experience the love and care of the family? What were society's expectations regarding children's attachment to their relatives? How did Byzantine authors describe the emotional bonds between children and parents, siblings and other relatives? The chapter will also address the issue of tensions and conflicts between children and their families. So, my goal is to explore the reasons that generated the conflicts, the way tension is represented in hagiographic sources, and how children and parents dealt with such conflicts? How have these tensions contributed to the dynamics of family relationships? Chapter five (Children and religion)
