Corporis formam caduci, membra morti obnoxia Induit, ne gens periret primoplasti ex germine, Merserat quem lex profundo noxialis tartaro.... _Cathemerinon_ ix. 10.[39] Rendered as a _rhythmus_, as in the hymn quoted by Bede,[40] the measure, besides ending with a stress, was often divided at the cæsura, to make stanzas of six four-stress lines; for the original line is long to handle singly; it tends to break. None of the other hymns taken from this poem of Prudentius is so familiar and so stirring as this of Fortunatus: Pange, lingua, gloriosi prælium certaminis, Et super crucis tropæo dic triumphum nobilem, Qualiter redemptor orbis immolatus vicerit. De parentis protoplasti fraude factor condolens, Quando pomi noxialis morte morsu conruit, Ipse lignum tunc notavit, damna ligni ut solveret.... _Carmina_ II. ii; MGH 27.[41] Possibly Fortunatus composed this as a _rhythmus_; more probably he thought of the soldiers’ marching stresses as reinforcing his _metra_. The long Bangor hymn ascribed to St. Hilary of Poitiers, and probably very old,[42] is quoted with admiration by Bede[43] as a metrum. Hymnum dicat turba fratrum, hymnum cantus personet; Christo regi concinnantes laudem demus debitam. Tu Dei de corde verbum, tu via, tu veritas, Iesse virga tu vocaris, te leonem legimus. Dextra patris, mons et agnus, angularis tu lapis, Sponsus idem vel columba, flamma, pastor, ianua. In prophetis inveniris nostro natus sæculo; Ante sæcla tu fuisti factor primi sæculi.... Folio 3 _recto_; AH 51: 264. It has the deeper significance of exhibiting an early form of medieval symbolism. The very different trochaic measure of the sixth-century Irish “breastplate” hymn, with abrupt pauses and rime, seems clearly a _rhythmus_, and deserves attention least of all for its art. _Lorica sancti Gyldæ Sapientis_ Suffragare, * trinitatis unitas, Unitatis * miserere trinitas. Suffragare, quæso, mihi posito Maris magni velut in periculo, Ut non secum trahat me mortalitas Huius anni neque mundi vanitas. Et hoc idem peto a sublimibus cælestis mi- litiæ virtutibus, Ne me linquant lacerandum hostibus, Sed defendant me iam armis fortibus.... AH 51: 358. 3. Other Measures
