The theme of this final work is the importance of artistic creation in preschool age and its influence on the development of the child. The work consists of a theoretical and practical part. The theoretical part of the paper deals with the importance and influence of art in upbringing, especially fine art. Fine art allows children to express their authenticity and to express through creativity what they feel, what they think about and the way they understand things and events around them. The development of children's visual language from the very beginning is then described and the great role of the environment for the development of the visual language is emphasized. Furthermore, this paper presents a historical overview of the view of children's artistic creation, which is not always valued in the way it is valued today. The development of pedagogy, psychology and other sciences influenced the changing view of children's art work. The influence of artistic creation on complete children's development, especially on cognitive and emotional development and on the development of creativity, has been recognized. The paper also describes the introduction of artwork in preschool institutions and its impact on children's development, as well as children's attitude towards works of art. In the second, practical part of the work, two artistic activities performed with children in kindergarten are described. In the first activity, the children painted with temperas, and as a spur and motivation was Rembrandt's painting The Return of the Lost Son and the story of the same name. In the second activity, the children designed, wrote and drew a picture book that builds on the story of the first activity. The aim of this final work is to raise awareness of the importance of artistic creation from an early age and to evaluate children's artistic work.
