The dictionary offered to the reader's attention differs from other mythological dictionaries, where the names of gods and heroes of myths of different peoples are usually presented (Avalokiteshvara, Bolotnyanik, Zeus, Perun, Hurakan, etc.) or sacred-symbolic objects and concepts (Tower, mirror, Mandala, etc.). In our dictionary, the reader is invited to familiarize himself with the theoretical concepts of the science of mythology (and not mythology as a system of plots, motives and images). The dictionary, therefore, is focused on the theoretical side of our science. At the same time, the categories and terms themselves ("mythology," "myth-making," etc.) are considered on the example of analyzing a work of art, which should greatly facilitate the understanding of theoretical material and show students how it can be used in practical activities - when analyzing text. The dictionary will help students better navigate one of the most important problems of both classical and modern philology - the problem of "myth and literature," will open up to the reader the methods of mythological analysis and the main categories of the method of myth restoration of an artistic text. At the same time, the main law of mythology should be well understood: the will to myth is determined by the metaphysical need for sacred being.
