His publications cover topics as varied as the Roman catacombs, the fragmentary mural paintings from excavated churches such as San Clemente and S.

Carol M. Richardson is Lecturer in the History of Art at the University of Edinburgh. Her book Reclaiming Rome: Cardinals in the Fifteenth Century (2009) was described as 'a milestone in the history not only of artistic patronage but also of the papacy in fifteenth-century Rome [which] will become a standard work for scholars to return to again and again' (Simon Ditchfield, Art History 34/1 (2011)). She has also edited a number of Open University textbooks which are widely used to teach history of art on both sides of the Atlantic. Joanna Story is Professor of Early Medieval History at the University of Leicester, specialising in interdisciplinary research into the history and archaeology of Europe in the age of Charlemagne.
