According to William, Gerbert used astral science to create an oracular head. Yet the earlier sources that William quoted ascribed Gerbert's talking head to demonic, rather than celestial, magic. This important change reflects the introduction of texts on astral science and divination into western Europe, specifically into England in the early twelfth century, while pointing to contemporary concerns about the intellectual and moral legitimacy of divination.
