Since time immemorial, humans have been both awed and guided by the power of the unknown. A basis of spiritual beliefs the world over is the abiding question, why?—a probing wonderment often followed closely by, what happens when we die?

Human belief systems provide structure that help us to make sense of the world, and yet the nature of our existence—and how we fit into the context of the cosmos—comprises some of the most beguiling mysteries of all. It’s no surprise that across cultures and throughout millennia, our search for meaning and connection with other worlds has inspired incredible creativity.

Spirit Worlds, forthcoming from TASCHEN on September 15, celebrates art’s relationship to other realms. More than 400 works spanning thousands of years, paired with essays and interviews with scholars and practitioners, illustrate our fascination with supernatural, from angels and celestial beings to darker forces like ghosts and demons.

The title marks the sixth installment in The Library of Esoterica series, which also includes titles like Plant Magick and Sacred Sites. Spirit Worlds clocks in at more than 500 pages, surveying death rites, altars, sacred temples, the messages of prophets, links mediums make with the other side, symbolic statuary, and more.

“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,” the publisher says.
