Summary: 
Antiphoner. "The Istanbul Antiphoner." 303 ff. Lacuna between ff. 203 and 204. 465 x 316 mm. Secular cursus. Staff Notation: Esztergom (Hungarian) notation for first 294 folios. Ff. 295-303 consist of additions in different scripts.
Description: 

Provenance (origin): the ecclesiastical province of Esztergom of medieval Hungary during the Angevin period (Dobszay, '"The Origin and Fate of the Codex,” p. 62).
Provenance (usage): Esztergom.
Provenance (subsequent history): During the Turkish occupation of Hungary (1526-1686), the codex was taken as booty to Istanbul (Ibid.).
Noteworthy details: In this codex are two complete Offices for Adalbert of Prague, the patron saint of the diocese of Esztergom: one for 23 April and one, commemorating the translation of Adalbert’s relics, for 6 November. According to Dobszay, the latter was a feast local to Esztergom (Dobszay, “The Liturgical Analysis of the Codex,” 47). The Sanctorale contains complete Offices for the following Hungarian saints: King Ladislaus, King Stephen I, Emeric and Elizabeth of Hungary. Added items at the end of the manuscript include two feasts prevalent in Hungarian sources: one for Queen Helen (mother of Emperor Constantine the Great) and one for Mary of the Snows (Ibid., 47, 52, 53).] The Istanbul Antiphoner is the only known source of the full Office for Andrew and Benedict that includes musical notation (Ibid., 51). Similarly, the Office for Anna contained in this source is known to appear in only one other source, the Esztergom Breviary (Ibid., 47).

Two invitatory tones found in the Istanbul Antiphoner have not yet been identified in other sources. They have been assigned the codes IS (associated with mode 2 antiphons) and IT (associated with mode 5 antiphons). The latter is included only in incipit in the manuscript. In addition, the invitatory tone labelled as “KN” in reference to the Klosterneuburg manuscripts (Liber Hymnarius, 162) is included in the Istanbul antiphoner. The incipit of what appears to be the ferial invitatory tone FE (owing to its usage in the manuscript) does not correspond to any of the full tones listed at the end of the book. It is associated once with a mode 4 antiphon and otherwise with mode 6 antiphons.
Marginalia that have not been indexed in this file owing to illegibility are referenced in the notes file (available from the CANTUS research office upon request).
There are two sets of foliation in pencil; in cases where the two sets do not match, the upper one (sometimes in parentheses) has been followed.
