From Dogma Part II: Amores Perros —
"It is night on the fourth of the curving terraces, high above the sea.
The stars are full out, known and unknown. Dante is halfway up the mountain….
It is half through the poem; half the whole is seen and said: hell, where grace
is not known but as a punishment; purgatory where grace and punishment are
two manners of one fact."
— Charles Williams, The Figure of Beatrice, Faber and Faber, 1943
