Constanze Witt of the Department Of Classics at the University of Texas posted the following to a medieval list.

Not all sensational finds come out of the ground! Augustine scholars will be delighted at the news of 6 previously unknown sermons’ being discovered through a library “excavation” in Erfurt’s Bibliotheca Amploniana. Isabella Schiller and colleagues from the Austrian Academy of Sciences discovered these works while studying an 800-year-old manuscript in the summer of 2007.

Concealed in a medieval parchment manuscript amongst 70 other religious texts are ca. 26 sermons attributed to Augustine, 3 of them on brotherly love and alms-giving. These were known previously only by their titles cited in Possidius’ Indiculum. One sermon is on the martyrs Perpetua and Felicitas, and another on the recently martyred Cyprian, the latter of which condemns the copious drinking that took place on saints’ feast days. The final sermon deals with resurrection of the dead and biblical prophecies.

The 12th c. mss came from England(?) to Erfurt as part of the enormous collection of more than 630 books donated by the physician and theologue Amplonius Rating de Berka to the ‘Collegium Amplonianum’ which he founded in 1412.
