“This new reference book is focused on Medieval Christian Nubia and its historical and religious context. This descends from the former Historical Dictionary of Ancient and Medieval Nubia (2004) that had combined both subjects, but new excavations and research have demanded a still deeper look at the often-neglected Christian civilizations on the Sudanese Nile. This is an extremely ample, comprehensive and deeper book by Lobban that neatly outlines and contextualizes the emergence and development of Christianity in Nubia. This region beyond the first cataract on the Nile contributed fundamentally to the development, continuity and distinctiveness of Mediterranean and African civilization evolving from the pre-Christian Greco-Roman period and evolved in the complex schisms within Christianity. This epoch was terminated by the rise of Islam in Sudan after almost 1,000 years, but actually lasted longer than the present period of Islam” Eugenio FantusatiProfessor, International Association of the Study of the Mediterranean and the Orient (ISMEO), Rome
