Professor Lesley Smith works on the medieval Bible, as both a physical and intellectual object. This ranges from close technical work with manuscripts of Bibles, biblical commentary, theology and pastoralia, to the exposition of commentary and theology, to investigation of the intellectual milieu of the schools in which the Bible was studied – the people and the products of this early university system, from the twelfth century onwards. In particular, Professor Lesley Smith explores the two-way link between the manuscript evidence and the intellectual evidence of these early schools – in modern terms, how technology affects what we learn and know, and vice versa. The study of the Bible has also led them to contribute to the study of medieval Jewish-Christian scholarship and relations.
