Professor Alan Deyermond was one of the leading British Hispanists of the last fifty years, whose work had a formative influence on medieval Hispanic studies around the world. There were several tributes to his work published during his lifetime, and it is fitting that this one, in his memory, should be produced by Tamesis, the publishing house that he helped establish and to which he contributed so much as author and editor right up to his death. The contributors to this volume are some of Professor Deyermond's former colleagues, doctoral students, and members of the Medieval Hispanic Research Seminar. Given Professor Deyermond's breadth of expertise, the span of the essays is appropriately wide, ranging chronologically from the thirteenth to the sixteenth century, and covering lyric, hagiography, clerical verse narrative, frontier balladry, historical and codicological studies. The volume opens with a personal memoir of her father by Ruth Deyermond, and closes with the draft of an unpublished essay found amongst Professor Deyermond's papers, and edited by his literary executor, Professor David Hook.
