This brief, popular work on confession, here for convenience abbreviated as QC, is ascribed to Robert Grosseteste (ca. 1168–1253), bishop of Lincoln (1235–53), in most of the known manuscripts, and circulated within many copies of collections of his sermons, in association with other texts by him, or on its own. This text enjoyed a very wide readership, as there are presently known to be thirty-six manuscripts of it (see below), all in English hands, of which eleven were copied in the thirteenth century (see MSS C, Cs, G, Gv, Hk, Js, Pt, R7, R9, U, and Z, below). Twenty-seven of these thirty-six copies were reported by S. Harrison Thomson in his catalogue, published in 1940, of Grosseteste's writings. The list below could probably be extended after further searching, especially in codices of theological or pastoral miscellanea, which are often inadequately catalogued.
