Abstract
De Martino offered Momigliano an opportunity to reflect on his own analogous yet different experience. The connection between the study of prehistory and the threat of the end of the world, and more generally, the idea that we need to respond to today's crisis by enlarging historical research to unknown and unpredictable phenomena might lead us to conclude that, at least momentarily, Momigliano's and De Martino's paths had touched. In reality, however, as Momigliano lucidly saw, theirs were parallel paths that could never meet. Studies that culminated in Il Mondo Magico had carried De Martino, albeit temporarily, outside Croceanism, and toward a more radical historicism immune from ethnocentric limitations, in particular with regard to Cassirer's works. Momigliano's detachment from Croceanism can be located between two divergent statements: that the sun had set on the idea of antiquitates, while also looking forward to the affirmation of a new antiquarianism under the guise of sociology or anthropology. It became increasingly clear as the years passed that for Momigliano all forms of historicism were unacceptable because they were threatened by relativism
