The fall of the Empire 
               Although the last Meroitic monarch known by name was Yesbokheamani
          (283 - 300 AD), 30 years later the dead rulers were still buried in
          the Northern cemetery of Meroe. On the other hand, an inscription
          of an Ethiopian king Aezana, discovered in the city of Axum and dated
          to c. 350 AD, reports a war with the Noba people and the conquest of
          Al-Butana. Probably at that time the kingdom of Meroe no longer existed.
          Whether the hegemony of Meroe collapsed due to an internal crisis,
          or whether its fall was partly brought about y raiding nomads from
          the desert, is a question that cannot be decisively answered...
        
The nomads build tumuli...
               The next two centuries, the so-called Post-Meroitic period, is one
          of the most mysterious and least recognized periods in the history
          of the Sudan. Monumental architecture and knowledge of writing disappeared
          altogether, and in the belt between Sennar and the Fourth Cataract
          there appear earth burial tumuli of the Tanqasi culture, today the
          only legible remains of the Noba nomad tribes who arrived at this region
          from the territories of modern Kordofan. An especially large and richly
          equipped burial ground was discovered in el-Hobagi. 
        
The Blemmyes - a wild headless race 
               The Meroitic inhabitants of Lower Nubia encountered arrivals using
          the Nubian language. These included the Nobatae who in 296 were apparently
          entrusted by Emperor Diocletian with the defense of the southern Egyptian
          frontier, and the Blemmyes from Eastern Desert, scornfully described
          by Pliny as "a wild headless race with eyes and ears rising directly
          from their shoulders". The latter were particularly devoted to the
          old Egyptian religion and each year would go on a mass pilgrimage to
          the sanctuary of Isis on the Island of 
Philae. The specific civilization
          that emerged from the fusion of these elements is named the X-Group
          or Ballana culture.
          
                  The nameless kings from Ballana and Qustul 
               It was in Ballana, and also at nearby Qustul, that the cemeteries
        of huge tumuli with burials of tribal rulers were found. The dead were
        equipped with immense splendor - the burial gifts included breathtaking
        crowns that used the symbolism of ancient Egyptian motifs, and highly
        precious silver vessels imported from territories of the Roman Empire.
        The political significance of those nameless kings is highly obscure.
        Probably we shall never know whether the two Nobatian rulers, Silko and
        Kharamazeye, mentioned in the inscriptions on the temple walls in Kalabsha,
        had also been buried in one of the Ballana tumulus graves...
