Delvaux was born into the new technological age, one of imagination and invention. He was fascinated by trains and trams, but his overriding passion was for Jules Verne's "Journey to the Center of the Earth" (1864), which he loved because of the fantastical worlds it created and its haunting illustrations by Édouard Riou. As the son of a lawyer, Delvaux was expected to follow in his father's footsteps, and so he embarked on a classical education. His imagination was fueled by the myths of Ancient Greece, most notably the story of Odysseus. He recalled a childhood fear of a skeleton that was displayed in his school music room. The skeleton's leering grin haunted his nightmares and served as fodder for his active imagination. All of these childhood influences left a lasting mark on his memory; he once explained that "youthful impressions, fixed once and for all in the mind, influence you all your life."
