A voyage through mysterious and haunted lands, the sixth volume of The Library of Esoterica delves into the art, rituals, and global mythologies of the spirit realms. Unearthing our complex beliefs around death, rebirth and resurrection, we explore the art, traditions and ancient stories of the afterlife. Through interviews with scholars and practicioners, insightful essays and over 400 works of visionary art, Spirit Worlds delves into the shadows of the supernatural, from dark domains of ghosts and demons to the light-filled lands of angels and celestial beings. Across more than 500 pages, we celebrate the ways in which we connect with both our ancestors and with ourselves, as we worship, mythologize and honor our dead. We study the rites of death around the globe, highlighting the ancient monuments and sacred temples we build out of our sorrow. We showcase the altars we create and the communities we nurture as we share our grief with our gods. We dive into the rituals that connect us to those we've lost. And we decipher the messages communicated to us from the other worlds by mediums and prophets, through the elaborate séances of the Spiritualists, and in the storied words of oracles and fortunetellers bent at their crystal balls. And finally, we showcase artworks that that channel not only the muse, but the unknown, eloquent voices and visions from the other side. In this expansive volume, we board the ferry across the storied river and enter the gloomy passages between lands, stepping across the threshold-to part the most sacred of veils.
