There came to my attention, in 1921, through the kindness of my colleague, Professor Frank Jewett Mather Jr., a manuscript of a Latin Life of St. Margaret, which he had recently purchased. Through his further kindness, I was permitted to examine and to transcribe the text of the manuscript, which was formerly in the possession of Sir Thomas Brooke, Bart., of Armitage Bridge. The manuscript is of vellum and measures × inches, being what we should now call a pocket volume. Indeed, the condition of the last leaf indicates that the book may have been some devout reader's constant companion before it was put into its present comparatively modern binding. It contains twenty-two leaves, of which nineteen are in a hand of the later fourteenth century, and the last three in a hand of the fifteenth century. Unless I am mistaken, both scribes were Englishmen. One may conjecture—though this is no more than a guess—that the second scribe was employed to complete the text because of some accident that had befallen the book. His work was crude in comparison with that of the first scribe, who wrote neatly, while he or a co-worker embellished the book with no less than nineteen boldly drawn and very interesting miniatures. The four pictures on the appended leaves are as rough as the script.
