St. Augustine.- Two fragments from Pseudo-Augustine In Cathedra S. Petri, decorated manuscript on parchment, in Latin, 2 strips cut vertically from a single leaf, now justaposed, remains of double column, 32 lines, written in a late Carolingian minscule, on recto three 1-to 2-line initials painted in red, on verso two 1-to 2-line initials in identical style, remains of larger initial in red, lower margin of one strip slightly cockled, portions of text lacking, double-sided wooden-framed and glazed, c.317 x 240mm.,12th century.

⁂ Two strips from a parchment manuscript, originally written in two columns, and containing a substantial portion from the Sermon on the Chair of St. Peter, at that time attributed to Augustine and included in the series De Sanctis (Sermo no. 190; PL 39, 2191). The sermon is an important piece of evidence for the Petrine office, the authority of the Pope, and generally the primacy of the Roman Church. It enjoyed a wide circulation in manuscript during the Middle Ages and its text was often included in collections of Augustine's sermons as well as in liturgical manuscripts, in order to be read on 22nd February, the date of the feast of Saint Peter in cathedra.

The text of this sermon, composed in about 460, is divided into two sections. Its first half justifies the solemnity of the feast and the foundation of the Church, including the famous statement from Matthew's Gospel (Mt 16,18): "You are Peter, and on this rock I will build my church". The content of its second half is quite different - the author denounces pagan superstitions, and especially funerary meals (the custom of placing food and wine on the tombs of the dead), still associated with the feast of the Chair of Saint Peter.
