This book offers a reconstruction of the repressed, concealed, and forgotten matriarchal religions and spirituality. The matriarchal background of the goddess figures found in Indian, Persian, West Asian, Egyptian, Greek, Celtic, and Germanic myths is reclaimed through a comparative and patriarchal-critical analysis. Building on this, it demonstrates how the symbolic and action patterns of matriarchal religions and spirituality continue to live on in international fairy tales. Furthermore, it shows through major epics of the European Middle Ages that the structure of matriarchal religions becomes the foundation for poetic themes in European literature, revealing the significant influence of very ancient matriarchal ways of thinking on our culture.
