coherence and exhibit an awkwardness alien to the style of Ambrose”. H. A. Daniel, in his Thesaurus Hymnologicus (1841–51) still mistakenly attributed seven hymns to Hilary, two of which (Lucis largitor splendide and Beata nobis gaudia) were considered by hymnologists generally to have had good reason for the ascription, until Blume (1897) showed the error underlying the ascription. The two hymns have the metric and strophic cast peculiar to the authenticated hymns of Ambrose and to the hymns which were afterwards composed on the model. Daniel gave no less than ninety-two Ambrosian hymns, under of “S. Ambrosius et Ambrosiani”. Similarly, Migne, in Patrologia Latina 17 (1845) edited Hymni S. Ambrosio attributi, without attempting to decide which hymns of the Old Hymnal are genuinely due to Ambrose. Modern hymnology has reduced the number of hymns for which Ambrosian authorship is plausible to about fifteen, including uncertain cases. The Maurists limited the number they would ascribe to St. Ambrose to twelve. Luigi Biraghi (1862) and Dreves (1893) raised the figure to eighteen. Chevalier is criticised minutely and elaborately by Blume for his Ambrosian indications: twenty without reservation, seven “(S. Ambrosius)”, two unbracketed but with a “?”, seven with bracket and question-mark, and eight with a varied lot of brackets, question-marks, and simultaneous possible ascriptions to other hymnodists. Only four hymns are universally conceded to be authentic: 1. Aeterne rerum conditor (OH 2); 2. Deus creator omnium (OH 26); 3. Jam surgit hora tertia (OH 17); 4. Veni redemptor gentium [= Intende qui regis Israel] (OH 34). With respect to the first three, Augustine quotes from them and directly credits their authorship to Ambrose. Internal evidence for No. 1 is found in many verbal and phrasal correspondences between strophes 4-7 and the “Hexaëmeron” of the Bishop. Augustine also appears to refer to No. 4 (to the third verse of the fourth strophe, Geminae Gigas substantiae) when he says: “This going forth of our Giant [Gigantis] is briefly and beautifully hymned by Blessed Ambrose”. Other attributions to Ambrose are due to Pope Celestine V (430), Faustus, Bishop of Riez (455) and to Cassiodorus (died 575). Of these four hymns, only No. 1 is now found in the Roman Breviary. It is sung at Lauds on Sunday from the Octave of the Epiphany to the first Sunday in Lent, and from the Sunday nearest to the first day of October until Advent. There are numerous
