This volume explores the ways in which representatives of different monotheistic traditions experienced themselves as “the other” or were perceived and described as such by their contemporaries. This central category – which includes not only those of different religions, but also converts, foreigners, sectarians, and women – is studied from various perspectives in a range of texts composed by Jewish, Christian, and Muslim authors during late antique and mediaeval times. Conceptualizations of such “others” are often intrinsically related to the idea of exile, another important category that is analysed in this work.
