Prague notation Two leaves from a Hymnal, in Latin, manuscript on paper [Czech Republic, late 15th century (after 1481)].Two leaves from a Czech hymnal, with later Prague notation. 290 x 210mm, 2 consecutive leaves, foliated 15 and 16 in pencil, and three small fragments (likely used as guards), 27 lines written in black ink in a cursive Gothic bookhand, later Prague notation on a 4-line staff in brown with C- and F-clefs, initials alternately in red or blue (edges a little frayed, some marginal thumbing).Provenance : (1) The leaves were ff.15-16, bound with 16 others (see Schøyen Collection MS 88) at the end of an incunable Psalter in a rare binding associated with Blasius Orger of Prague, printed at Magdeburg by Bartholomaeus Ghotan in 1481 (Proctor 2753) and sold at Sotheby's New York, Incunables from the Schøyen Collection , 12 December 1991, lot 36. The incunable, with the leaves still bound inside, contained a purchase inscription of 'Adamus Derogarius, decanus' dated 1592. A hymn for the Feast of St John the Baptist, 'O nimis felix' has been added in a 16th-century hand on the verso of the first of the two leaves offered here. The incunable was sold by: (2) Björck & Börjesson, Stockholm, One Hundred interesting books on various subjects , cat. 520 (1987), no 128, and subsequently: (3) H.P. Kraus, New York, acquired in 1988 by: (4) Schøyen Collection, where these leaves became MS 87.Text and music : The leaves were described in both the Björck & Börjesson and Kraus catalogues as containing metrical hymns. Likely from a Hymnal, the hymns included here are from the Feasts of Corpus Christi, beginning on f.15: 'In mortem a discipulo suis tradendus emulis', followed on the verso by the vespers hymn for the Feast of St John the Baptist: 'Ut queant laxis resonare fibris', and on f.16v 'Aurea luce et decore roseo' from the Feast of Sts Peter and Paul, here ending: 'Ianitor celi doctor orbis pariter iudices [saecli vera mundi lumina]'. The later Prague notation, where the notes are represented by rhombuses is comparable, for example, to that found in a Gradual from Hradec Králové (CZ-HK 40 [II A 2]).
