Gerald of Wales (c. 1146 – c. 1223), also known as Gerallt Gymro in Welsh or Giraldus Cambrensis in Latin, archdeacon of Brecon, was a medieval clergyman and chronicler of his times. Born around 1146 at Manorbier Castle in Pembrokeshire, Wales, he was of mixed Norman and Welsh blood, his name being Gerald de Barri.

Geralds writings in good quality Latin, based on a thorough knowledge of Classical authors, reflect experiences gained on his travels as well as his great knowledge of the standard authorities and he was highly respected as a scholar in his time and afterwards. The noted scholar Edward Augustus Freeman said he was the father of comparative philology, and in the preface to the last volume of Geralds works in the Rolls Series, he calls him one of the most learned men of a learned age, the universal scholar. [5] His writings were prolific, running to about ten volumes in modern printed editions. Gerald was a man of strong opinions whose works are frequently polemical, including bitter attacks on his enemies, but also had an intense curiosity recording much valuable detail of everyday life in his ethnographic works.

It is generally agreed today that his most distinguished works are those dealing with Wales and Ireland, with his two books on his beloved Wales the most important: Itinerarium Cambriae and Descriptio Cambriae which tell us much about Welsh history and geography and reflect on the Cultural relationship between the Welsh and the English. Gerald, despite his desire for an independent Welsh Church and admiration for parts of Welsh life, was very loyal to Norman Marcher rule regarding the Normans as more civilised than the Welsh, a feeling reflected in his writings.
