Among the manuscript fragments in the Archivio comunale of Sutri (Province of Viterbo), Italy, are four consecutive folios of an Old-Roman antiphoner of the later eleventh century. The two bifolios are now identified as fragments 141 (Frammenti teologici 40) and 141bis (Frammenti teologici 41). These fragments, which preserve music for the feasts of Sexagesima, Quinquagesima and Ash Wednesday, are remnants of what appears to be the oldest witness of Old-Roman music for the office. When added to the two surviving antiphoners (London, British Library, Add. MS 29988, of the twelfth century, and Vatican City, Biblioteca Apostolica Vaticana, MS San Pietro B 79, of the end of the twelfth century) and two recently discovered fragments (in Frosinone and Bologna), the Sutri fragments bring to five the number of Old-Roman antiphoners of which at least some evidence survives. It begins to appear that manuscripts of this music were once not so rare. The Sutri fragments show some unusual liturgical characteristics that provide new information on the Roman liturgy; I will discuss these aspects shortly.
