Only forty-two manuscripts were digitized this week, the first full week of June for 2023. Continuing the pattern-ish of the last weeks, Vat.lat, with twelve, and Ott.lat, with eleven are the two most popular fonds. Following up is Var.ar with eight, and then a large number of smaller sets. Two each were contributed by Barb.lat and Reg.gr, and one from Barb.gr, Barb.or, Borg.ar, Capp.sist, Chig, Ross, and Vat.turc, which is the largest spread of singletons I've yet seen.

To the right is the first page, f.2r, from another of the glorious early 16th C chant manuscripts from the Sistine Choir, Capp.sist.37. This one is a Graduale which contains the chants for the mass. It would be the first one in a multi-volume sequence, as it begins with "Ad te levavi" the introit for the first Sunday in Advent, which is usually considered the start of the liturgical year. Due to possessing the arms and motto of Pope Julius II, this volume can be dated to 1503-1513. One interesting detail about this manuscript, only visible by browsing many images at once, is the huge difference in hue between the hair and flesh sides of the parchment. If you're wondering why the first page of text is foliated as f.2r, that's because f.1r was a later addition to the manuscript, recording the restoration of the manuscript by Cardinal Ottoboni to the library in 1724.

Below is a line of music from f.41r of Barb.lat.4165 a 17th C collection of songs. This section of Barb.lat, in the 41XX range contain a set of 19 similar oblong musical books, all with the Barberini bee heraldry on the cover, and all from the 17th C. Many contain named composers, including the biggest names of the 17th C, but this particular volume is entirely unattributed. This line of music comes from a song whose first line is "Deh, m'ascondi, amica notte", which is elsewhere sourced to the 1692 Venetian opera ibraim Sultano with music composed by Antonio Gandolfo da Catania.
