Refusing offers of several university posts, Orsi decided to concentrate on field research and publications. During his studies, he discovered the prehistoric zone of Colombo at Mori in Trentino. After a brief period in a teaching post at Alatri, he took a position at the general directorate of antiquities and fine arts, and then the "Biblioteca nazionale centrale di Firenze" (National Central Library of Florence).
