The present book is a compilation of studies on narratives of mythical origins in different cultures written by outstanding specialists. It aims to provide a broad view on creation-myths from different times and areas of the world with a particular focus on how these texts contributed to the conception of the past as "universal history", as a common origin of mankind or as the great opening, the theatrum mundi. On the other hand, the purpose of this book is to study the phenomenon from a typological point of view, analyzing the specific characteristics of this particular type of texts, rather than finding influences between the different cultures in the genesis of these narratives.
