The current book is the newer version of the doctoral dissertation defended at the University of Tartu, Faculty of Theology in 2010. The printed edition was published in very small numbers (The God Enki in Sumerian Royal Ideology and Mythology. Dissertationes Theologiae Universitatis Tartuensis 19. Tartu University Press 2010) by the University Press of Tartu as the procedures of defending the doctoral degree in Estonia demand. The publishing of the new edition of the book is necessitated by the lack of printed copies of the 2010 monograph which several libraries, scholars and students have wished to obtain fromthe author.
