My apology for reverting to this subject is a recent article by Mr. W. C. F. Walters in the April number of the Classical Quarterly for 1910 on the signatures in the Vatican Codex . Mr. Walters does not seem to have been aware that this manuscript, though not of direct value in the constitution of the text of Livy, is one whose interest from a palaeographical point of view has long been recognized. A number of articles have been written (...) concerning it, most of which deal with the signatures, the subject of Mr. Walters' paper, more fully and more accurately than he has done. Beyond giving the signatures, two of them incorrectly, Walters does nothing more than to conclude that there were eight scribes, who copied 42 quaternions. But a great deal more than this is known about the scribes and the manuscript. In fact, thanks to the ingenious combinations of Chatelain and Traube in piecing together the hints suggested by the signatures, more is known about this particular manuscript and the circumstances under which it was made than is the case with any other manuscript of a classical author of so early a date. It may therefore be worth while to summarize the known data concerning the manuscript, with a brief account of how they were worked out, referring the reader for the details to the articles mentioned in the footnotes.
