Campo's subjects range from the canonical to the esoteric. She writes stylishly about Shakespeare and Doctor Zhivago, as well as flying carpets, sprezzatura, and the theophagic origins of the Latin liturgy. Her passion for Marianne Moore and T. S. Eliot makes her a modernist, but like these American counterparts she is a modernist preoccupied by the deep past and by her desire to escape from personality through sustained attention to form. For Campo, writing was a spiritual discipline, and her sentences are at once wonderfully and wildly alive and serenely self-effacing. "I have written little," she once said, "and would like to have written less."
