This Festschrift celebrates the significant contribution of the Revd Dr John Clark to the study of monastic and mystical theology in the pre- and post-Reformation periods. As he is represented in the foreword (Alec Graham) and the epilogue (James Hogg) Dr Clark is among the last in a formidable line of Anglican scholar-priests, pursuing scholarship in parallel with pastoral responsibilities. The volume presents papers and personal tributes from fifteen friends reflecting the varied milieu – academic, Anglican, monastic – in which he has worked in both capacities. Clark is perhaps best known for his work on Walter Hilton, and three essays examine the Augustinian and his analogues: S. S. Hussey considers the affiliations between the Scale and the Cloud of unknowing; Vincent Gillespie uses Thomas Betson's Registrum to recover the role of Syon Abbey in the transmission of Hilton's works; and James Hogg reports on preparations for an edition of Richard Methley's Latin translations of the Cloud and Porete's Mirror. Clark's most recent project has been to recover the writings of the Benedictine, Augustine Baker, and five further essays examine his life, thought and legacy: Anselm Cramer considers the books of Baker's community; Margaret Truran, Blosius, Baker's favourite; Teresa Rodrigues his ‘human traits’ displayed in his Holy wisdom; and Benedicta Rowell and Geoffrey Scott assess his impact on later generations of English monks and nuns. The remainder is a miscellany of studies in fields adjacent to Clark's own. Andrew Louth explores the eastern theology of Evagrios, Jan de Grauwe and Francis Timmermans, and Harald Goder, analyse aspects of Carthusian capitular government, Cantera Montanegro considers the Carthusians in fifteenth-century Castile, Raphael Witowksi recovers the career of Jacobus de Paradiso, and Joseph Gribben the chapters of the English Premonstratensians. As with any Festschrift, this collection as a whole will appeal largely to Clark's own (admittedly wide) circle, but there are valuable studies here – Gillespie, Gribben, de Grauwe and Timmermans – which merit a wider audience.
