In the long history of alternative comics, few works are as venerated, or as underseen, as Saga de Xam, the legendary French graphic novel by Nicholas Devil and Jean Rollin. Originally published in 1967 in limited quantities, the book earned a devoted cult following for its innovative psychedelic visuals and avant-garde sensibilities, even as it spent decades out of print. Saga de Xam chronicles the adventures of Saga—a blue-skinned female alien on a mission to Earth—as she encounters both the cruelties and the possibilities of human civilization, from prehistory to the Middle Ages to the radical 1960s.
