Ad augusta per angusta is less familiar than ad astra per aspera but in some ways more precisely descriptive of the poetic experience, since it emphasizes the constricting narrowness of the path rather than the generalised experience of hardship.
The image of a narrow passage opening onto grandeur is deeply embedded in the mystical tradition — the strait gate of
Matthew 7:14, the eye of
the needle, the birth canal — and connects formal poetic constraint to spiritual
discipline. Students should explore how the constraint of poetic form — the fourteen lines of the sonnet, the syllabic discipline of haiku, the terza rima of Dante — functions as the angusta (narrow strait) through which the poem must pass to arrive at its augusta (greatness). The Jesuit tradition of spiritual discipline, which shaped both
Hopkins and
Donne, is closely connected to this concept.
