The Kalendar of the Second Prayer Book of Edward VI (1552) differs from that of the First Prayer Book, by omitting St Mary Magdalene and St Barnabas (June 11): but this latter would seem to have been omitted only _per incuriam_, as the collect, epistle, and gospel are found in the body of the book; and by the insertion of the following black-letter days, St George (April 23), Lammas (Aug. 1), St Lawrence (Aug. 10), St Clement (Nov. 23), together with Term days, ‘Dog days,’ ‘Equinoctium’ (March 10) and the days of the entrance of the sun into the several signs of the zodiac. It is an interesting problem how in the Prayer Book, which represents emphatically the action of the more thorough-going of the Protestant party, these black-letter days came to be inserted. In the Prayer Book of 1559 ‘Barnabe Ap.’ reappears; the astronomical notes are somewhat fuller, and the hours of the rising and setting of the sun at certain dates are recorded. As regards the black-letter days in the present Kalendar of the Church of England we have first to call attention to the Latin Prayer Book issued by the authority of Elizabeth in April 1560. It seems to have been ready for the press as early as Aug. 11, 1559. Its Kalendar is adorned with a great crowd of black-letter saints; and there are but few days blank. In 1561 appeared a new Kalendar in English, the work of Ecclesiastical Commissioners acting upon a royal letter. The Commissioners were directed to peruse the order of the lessons throughout the year, and to cause some new Kalendars to be imprinted, ‘whereby such chapters or parcels of less edification may be removed, and others more profitable may supply their rooms.’ As a matter of fact the Commissioners went beyond their instructions, and inserted in the Kalendar the names of black-letter saints almost as they were a century later approved by Convocation in 1661. These were inserted in the later issues of Elizabeth’s Prayer Book. After the accession of James I the Birth-Day of Queen Elizabeth ceased to appear in the Kalendar at Sept. 7, and St Enurchus takes its place. The only changes made in 1661 were the addition of Ven. Bede (May 27), St Alban (June 17), and the continuance of St Enurchus (Sept. 7), together with the shifting (probably through mistake) of St Mary Magdalene from July 22 to July 21. With regard to the date of St Mary Magdalene a reference to the photo-zincographic facsimile of the Black-Letter Prayer Book, in which corrections were made at the last revision, will show at once how easily the scribe who copied from this book might make the mistake.
