O Heilige Dreifaltigkeit. [Morning.] First published in his Kriegesman, Leipzig, 1593, in 7 stanzas of unequal length, repeated in 1608, in 8 stanzas of 4 lines. Both forms are in Wackernagel, v. p. 197; and the second in Noldeke, 1857, p. 53; and, omitting stanzas vi.-viii., as No. 1126 in the Berlin Geistliche Lieder, ed. 1863. In 1593 it was entitled "The ancient Sancta Trinitas et adoranda (Jnitas in German)" but it is rather a versification of the Prayer for Wednesday evening in J. Habermann's Gebet Buck (Wittenberg, 1567). The translations in common use, both of the second form, are:—
2. O holy, blessed Trinity, Divine. A good translation of stanzas i.-v. by Dr. C. H. L. Schuette, as No. 295 in the Ohio Lutheran Hymnal, 1880.
