De gestis Giraldi is a narrative of the deeds of Gerald of Wales (c. 1146-1223), written in the third person but actually by Gerald himself, and framed as the biography of a bishop although Gerald never became a bishop. Gerald was born in south-west Wales of mixed Norman and Welsh descent and educated at Gloucester and in Paris. He worked for Henry II and Richard I, by whom he was valued as an intermediary between the king and Gerald's relations, who included the leading Welsh king, Rhys ap Gruffudd, and many of the first English settlers in Ireland. When elected bishop of St Davids, Gerald was sent by his fellow-canons to Rome to secure his own consecration and metropolitan status for St Davids; ultimately, both cases failed, defeated by the combined power and resources of the English state and church. Near the beginning of this final part, the single MS breaks off, but the chapter-headings show that much of the substance is preserved in another work by Gerald. His career spanned Wales, Ireland, and England, Paris and Rome, and De gestis Giraldi offers a vivid and personal view of them all. This volume has been prepared from a critical study of the extant manuscript, and features an accompanying English translation. The edition supports the translation and text with an authoritative introduction, extensive historical notes, and critical study of the work.
