This article is an attempt to assemble the vocabulary related to war found in Nubian written sources (primarily manuscripts) and discuss the insights it offers about warfare in Christian Nubia. All four languages used in medieval Nubia are examined, but the focus is on Old Nubian. Saint Epimachos, Saint Mercurios, Saint George, and the Archangel Michael are the personae around which pivot the narratives that offer insights into weapons, offices, and practices in the otherwise very scarcely documented military of Christian Nubia.
