This is the second part of a two-volume documentary biography of the fourteenth-century Carmelite, St. Andrew Corsini, who was a lecturer in theology, Provincial of the Tuscan Province of Carmelites, for a brief period, during which many died because of plague, and a reforming Bishop of Fiesole, which is on a mountaintop overlooking Andrew's native Florence. The relevant documents are translated and analysed in order to clarify the various disputed questions concerning the life of St Andrew Corsini. These include such historical issues as the nobility or otherwise of the Corsini family into which he was born, the identity of his mother, the years of his birth and episcopal election. Some specifically documentary issues are also considered, notably that concerning the apparent contradiction between the evidence of the Ricordanze of St Andrew's brother, Matteo, and the two earliest extant Lives of the Saint from the fifteenth century, concerning the Saint's date of birth.
