abstract:
This volume presents the first critical edition and translation of the corpus of medieval Welsh medical recipes traditionally ascribed to the Physicians of Myddfai. These offer practical treatments for a variety of everyday conditions such as toothache, constipation and gout. The recipes have been edited from the four earliest collections of Welsh medical texts in manuscript, which date from the late fourteenth century. A series of notes provides sources and analogues for the recipes, demonstrating their relationship with the European medical tradition. The identification of herbal ingredients in the recipes is based on pre-modern plant-name glossaries rather than modern dictionaries, and has led to new interpretations of many of the recipes. Comprehensive glossaries allow the reader to find any recipe based on the ingredients and equipment used in it or the condition treated. This new interpretation of these texts clearly shows that they are not unique, but rather form part of the medical tradition that was common throughout Europe during the Middle Ages.

abstract:
The urban culture of medieval Swansea, which provided the political context for William Cragh and his rebellion, represents only one aspect of the Marcher lordship of Glamorgan. Within the same lordship, Welsh gentry families engaged with national politics through a literary culture shared with their English neighbours. This paper looks at some of the most significant manuscripts associated with south Wales in the fourteenth and fifteenth centuries, including the ‘Red Book of Hergest’ and National Library of Wales MS Peniarth 50. This latter manuscript is particularly noteworthy for its multilingual contents and for its large collection of political prophecy in Welsh, English and Latin, testifying to Welsh involvement in English politics. The paper argues that Welsh literary culture was a strong element in Glamorgan Marcher society and that an elite group of Welsh gentry were at the heart of a mobile network of scribes, poets and manuscripts.

abstract:
Much of the corpus of medieval Welsh prophetic poetry, comprising as it does diverse and complicated strands of political, mystical, religious, and legendary material, has not previously been systematically studied, or even printed. The introductory chapter of this thesis makes a preliminary exploration of the historical context of the prophecies, the nature of their propagators and audiences, and also the influences prevalent on the authors, be these intellectual and literary influences, or sub-conscious and psychological influences which fall into the realm of anthropology. There follow editions of the Welsh prophetic poetry found in Oxford, Jesus College, MS cxi, and Aberystwyth, National Library of Wales, MS Peniarth 50. These two manuscripts, dating from the fourteenth and fifteenth centuries respectively, provide a significant cross-section of the medieval Welsh prophetic poetry extant. Detailed textual analyses of the poems with text, translation, and notes, examine language and metre, investigate references to persons and places, and seek to identify conventional prophetic elements. From a historical point of view, the prophetic texts are compared with contemporary chronicles, as reflections of contemporary historical thinking. Some attention is also paid to the material's wider manuscript context, and its transmission. This sheds light on the prevailing cultural and intellectual climate as well as providing invaluable help in the interpretation of individual prophecies.
