From the spectral raps of the Fox Sisters to the rise of the Ouija board, Brandon Hodge guides readers through two centuries of spiritual innovation—exploring the haunted technologies born from our longing to pierce the veil between life and death. A unique fusion of esoteric history, visual culture, and ghost story, this richly illustrated, large-format volume reveals the occult ingenuity of mediums, inventors, and mystics who crafted writing planchettes, talking boards, spirit trumpets, and other strange apparatus to reach beyond the grave. With original photography, archival ephemera, and gripping historical narratives, Supernatural Machines brings to light a forgotten chronicle of technological mysticism. Each of its 14 chapters is a portal to the past, a captivating read accompanied by stunning photographs, detailed illustrations, and haunting accounts that breathe life into the arcane artifacts that have captivated the imagination of our ancestors and ourselves.
