An extraordinary piece of scholarship.' - James Ginther, Department of Theological Studies, St Louis University ‘Mantello & Goering have made available to a broad audience a valuable primary source collection depicting thirteenth-century social, religious, and institutional developments seen through the episcopate of one of the Middle Ages' most formidable bishops… This is a wonderful piece of scholarship that is both easy and a pleasure to read. ’ - Andrew Fogleman; Comitatus: A Journal of Medieval & Renaissance Studies: vol 42:2011 ‘This accurate, stylish and thoroughly annotated translation of the letters of Robert Grosseteste will make one of the most important collections of correspondence from the Central Middle Ages accessible to new generations of students.’ - Julian Haseldine (The Journal of Medieval Latin, vol 21:2011) ‘This is a splendid piece of scholarship that will bring Grosseteste’s letters, and thereby Grosseteste the man, to a wider audience.’ - Neil Lewis (The Review of Metaphysics; vol 65:04:2012)
