Reverse. Nilus recumbent, crowned with lotus, himation over lower limbs, holds in right hand cornucopiae, from which springs infant genius pointing at letters IS. Reed in left hand. Left arm rests on elephant (or hippopotamus).
About Nilus, see previous coin. The infant genius is intriguing. The genius is the individual instance of a divine nature that is present in every individual person, place, or thing. The Greeks called their genii "daemons". The concept extended to some specifics: the genius of the theatre, of vineyards, and of festivals, which made performances successful, grapes grow, and celebrations succeed, respectively.
Which genius are we talking here and what is the meaning of "IS"? You tell me!
