translations into English, of which that by Cardinal Newman is given in the Marquess of Bute's Breviary (trans. 1879). The additional eight tunes and/or hymns credited to St. Ambrose by the Benedictine editors are: (5) Illuminans altissimus (OH 35) Epiphany; (6) Aeterna Christi munera (OH 44) Martyrs; (7) Splendor paternae gloriae (OH 8) Lauds, Monday; in Mode 1 this is both tune and words, but a second tune, to the words, was called 'Winchester New'. (8) Orabo mente dominum (now recognised as part of Bis ternas horas explicans, OH 19); (9) Somno refectis artubus (NH 14); (10) Consors paterni luminis (OH 51, NH 17); (11) O lux beata Trinitas (NH 1); (12) Fit porta Christi pervia (NH 94). The Roman Breviary parcels No. 6 out into two hymns: for Martyrs (beginning with a strophe not belonging to the hymn (Christo profusum sanguinem); and for Apostles (Aeterna Christi munera). No. 7 is assigned in the Roman Breviary to Monday at Lauds, from the Octave of the Epiphany to the first Sunday in Lent and from the Octave of Pentecost to Advent. Nos. 9, 10, 11 are also in the Roman Breviary. (No. 11, however, being altered into Jam sol recedit igneus. Nos. 9–12 have verbal or phrasal correspondences with acknowledged hymns by Ambrose. No. 8 remains to be considered. The Maurists give it to Ambrose with some hesitation, because of its prosodial ruggedness, and because they knew it not to be a fragment (six verses) of a longer poem, and the (apparently) six-lined form of strophe puzzled them. Daniel pointed out (Thes., I, 23, 24; IV, 13) that it is a fragment of the longer hymn (in strophes of four lines), Bis ternas horas explicans, and credited it to Ambrose without hesitation. The 18 hymns attributed to Ambrose by Biraghi (1862) are 1–7 above, and the following: Nunc sancte nobis spiritus; (OH 20) Rector potens, verax Deus Terce (Roman Breviary); (NH 10) Rerum Deus Tenax Vigor Sext (Roman Breviary); (OH 43) Amore Christi nobilis None (Roman Breviary); Agnes beatae virginis; (OH 39) Hic est dies verus dei; Victor nabor, felix pii; Grates tibi Jesu novas; (OH 42) Apostolorum passio; Apostolorum supparem; ; Jesu corona virginum office of virgins (Roman Breviary). Biraghi's list received the support of Dreves (1893) and of Blume (1901), but 20th-century scholarship has tended to reduce the number of hymns attributable to Ambrose. Helmut Gneuss (1968) accepts only
