Regular star polyhedra in the nineteenth-century Italian treatise

During the Unification of Italy, great mathematicians were involved in the writing of works that were educationally effective and closer to the scientific results that were just being achieved at the time ([8]). In 1858 was published the Trattato di Geometria Elementare,([5]) Giovanni Novi’s Italian translation of the French textbook by Antoine Amiot, Leçons nouvelles de géométrie élémentaire ([1]) Novi’s substantial contribution was to integrate the French treatise with theories that had just been developed. A subject on which he dwells are regular star polihedra, starting from theories developed by L. Poinsot, J.L.F. Bertrand and A.L. Cauchy
