The obverse portrait is realistic and rugged.

The eagle was the minister of Jove lightnings. Indeed, the outstretched wings suggest  jagged flashes of lightning. The type was one of the commonest used to represent the might of the Roman Empire, as well as the primitive and collective symbol of all father-figures.
