Abstract
The Genius of men and the Iunones of their wives are not only a feature of Roman religion, but also a special category of the deities of ancient polytheism, since they are born and die. They therefore shed an original light on the world of Roman gods, which was generally not understood outside Rome and Italy, and which even posed problems for Romans in public worship, when it came to sacrificing to the Divine Augustus, from AD 14 onwards.
