The Evidence of MSS. Themselves
We have to depend, of course, on the evidence of the MSS. themselves. It was happily a common practice to write on the fly-leaf or first leaf Liber (Sancte Marie) de (tali loco). This is decisive. Then, again, some libraries devised a system of press-marks, such as "N. lxviii.," let us say. You find this in conjunction with the inscription of ownership; it is a Norwich book, you discover, that you have in hand, and all books showing press-marks of that form are consequently Norwich books too. Or you will find the name of a donor. "This book was the gift of John Danyell, Prior." Search in Dugdale's Monasticon will reveal, perhaps, that John Danyell was Prior of St. Augustine's, Bristol, in 1459. A clue to locality will often be given in such a case by the monk's surname, for it was their custom to call themselves by the name of their native village. Thus, a monk named John Melford or William Livermere will be a Suffolk man, and the abbey in which he was professed is likely to be Bury. Coming to later times, it is apparent that at the Dissolution groups of books from a single abbey came into the hands of a single man. If I find Dakcombe on the fly-leaf of a MS., I am almost entitled to assume that it is a Winchester book: John Stonor got his books from Reading Abbey, John Young drew from Fountains, and so forth. Lastly, and most rarely, you are justified in saying that the handwriting and decoration of this or that book shows it to have been written at St. Albans or at Canterbury. Hitherto the instances where this is possible are few, but I do not doubt that multiplication of observations will add to their number.
In questioning a MS. for any of these indications (except the last) you must be on the look-out for signs of erasures, especially on the margins of the first leaf and on the fly-leaves at either end. Here the owner's name was usually written. Often it was accompanied by a curse on the wrongful possessor, and at the Dissolution there were many wrongful possessors, who, whether disliking the curse or anticipating trouble from possible buyers, thought it well to erase name, and curse, and all. They seldom did it so thoroughly that the surface of the vellum does not betray where it was, and it can be revived by the dabbing (not painting) upon it of ammonium bisulphide, which, unlike the old-fashioned galls, does not stain the page. Dabbed on the surface with a soft paint-brush, and dried off at once with clean blotting paper, it makes the old record leap to light, sometimes with astonishing clearness, sometimes slowly, so that the letters cannot be read till next day. It is not always successful; it is of no use to apply it to writing in red, and its smell is overpowering, but it is the elixir of palæographers.
Yet, when all has been done, there is a sadly large percentage of MSS. which preserve an obstinate silence. They have been rebound (that is common), and have lost their fly-leaves in the process, or, worse than that, they have lain tossing about without a binding and their first and last quires have dropped away. In such cases we can only tell, from our previous experience in ancient handwritings, the date and country of their origin.
