P-G (Guimarães) Arquivo Municipal Alfredo Pimenta N 099
The office for St. Hilary of Poitiers found in this fragment is quite rare and it appears to have had a relatively small distribution. For a discussion on another Iberian fragment which contains the beginning of the same office see Kathleen E. Nelson, ‘Observations on an Early Twelfth-Century Antiphoner Fragment at Toledo’, in Concordis Modulationis Ordo Ismael Fernández de la Cuesta In Honorem, Robert Stevenson and Emilio Rey Garcia (eds.), Inter-American Music Review, 17 (2007), 17-24.
The axis of the notation is slightly slanted to the right. Medium size neumes. Red line. Custodes. The difference between a lozenge and a more or less square punctum is not always clearly defined. A complicating factor in reading the mode of the chants is the fact that the lozenge is not used consistently. The lozenge was used either isolated or as part of a descending pattern of two or more notes on one syllable. There are two consecutive lozenges forming a clivis on fol. Br, right column, first line, over ‘me’.
