The portrait album, mentioned in the Preface as residing in Trinity College’s Wren Library, was little known for many years. It is a very large, well-bound volume, with each portrait mounted on its own stout page. (Henceforth, it is referred to as the “Wren Library album”.) The portraits are the mid-nineteenth century equivalents of modern-day graduation photographs: each subject wears an academic gown and holds a mortar board. All figures are shown three-quarters length, seated. Though the bodies and backgrounds are freely and rapidly sketched, in rather conventional poses, the heads are drawn with great skill and finesse.
