Antoninianus (Coin) Portraying Empress Marcia Otacilia Severa

The front (obverse) of this coin portrays a bust of Otacilia Severa diademed and facing to the right. The back (reverse) depicts a hippopotomus to the right. This coin was issued to commemorate the Roman Millennium. The lavish birthday celebration featured one thousand gladiators who fought to the death and thousands of exotic animals like this hippopotamus, native to Egypt. Supplying the Romans with African animals for the games was a flourishing business.
