��The true explanation of the omission of the last flat or sharp from the signature referred to on p. 493 &, is probably to be found in the in- fluence of the ancient modes.

SISTINE CHAPEL, ARCHIVES OF THE. For centuries past the jealousy with which these archives have been guarded by the Capellani Cantori Pontificii, their official custodians, has led to the circulation of many mysterious re- ports concerning them. All the trustworthy information we formerly possessed on the sub- ject is contained in a few scattered notices in the works of Adami 1 and Baini ; 2 and this amounted to little more than the certainty that they contained a priceless collection of works by the Ecclesiastical Composers of the I5th and 1 6th centuries. A large proportion of these treasures was, however, destroyed by fire, during the sack of Rome in 1527.* Again, between the years 1678 and 1688, further havoc was made, through the carelessness of the then ' protet- tore,' Cardinal Rospigliosi, after whose death, in 1688, it was found that numberless title-pages, and other portions of the finest MSS., had been stolen, for the sake of the miniatures and illuminations with which they were adorned. 4 Between the years 1721 and 1724, the greater number of volumes in the collection were re- bound, and ' restored ' by order of Pope Innocent XIII. Some volumes may possibly have been

��preserved by this process; but the operation was performed with such carelessness, that works, and parts of works, were bound to- gether at random, only because they happened to correspond in size, while the edges were so ruthlessly cut down, that, in many cases, clefs, initial letters, and composers' names were com- pletely cut away. Finally, during the occupation of Rome by the French revolutionary soldiers, in 1798, a certain ' citoyen' Mes'plet, who was nom- inated ' Commissaire des Beaux Arts/ took possession of the keys, but was recalled before much harm had been done ; and, though the volumes were soon afterwards removed to a room used for the breeding of poultry, and placed in the custody of the hen-wife, Baini found them, after the departure of the French, much less in- jured than could have been reasonably expected. 5
Until within the last few years, this was all that we knew, in connection with the archives. But all doubts are now removed. By permission of Pope Leo XIII, Dom. Fr. Xav. Haberl, Director of the School of Church Music at Regensburg, began, in the year 1883, an ex- haustive critical examination of the Archives, and, after continuous study, has published a complete bibliographical and thematic catalogue of the Collection, 6 containing a mine of informa- tion entirely new to the public.
From this most valuable work we learn that the collection contains 269 numbered volumes, and many others not numbered, mostly in large folio, written on vellum, or thick hand-made paper, bound in white or brown leather, with heavy clasps of steel or brass, and adorned with mag- nificent illustrations by the great masters of the 1 5th and i6th centuries. The MSS. date from the year 1458, to the end of the Polyphonic period ; and the voice-parts are generally arranged on opposite pages, in the form called Cantus later alls? Of the numbered volumes, 224 are in MS. and 45 printed. In 26 volumes the music is Gregorian. Among the printed works, are six volumes published by Petrucci 8 (Nos. 235 238), the twelve volumes of Masses, and nearly a complete set of the other works, by Palestrina, published during his life-time and that of his son Igino. Compositions by Pales- trina are also continued in 6 1 of the MS. volumes, which include 44 Masses, 104 Mo- tets, Irnproperia, Lamentationes, Miserere, and Magnificat.
A few volumes in the collection are of special interest.
No. 22 contains the earliest copy of the Missa Papse Marcelli in existence, When the three Masses written by Palestrina in 1565 were submitted for approval to the Commission of Cardinals, it was ordered that copies should be made of them, for preservation in the archives, and, that the Missa Papae Marcelli should be
