I think, therefore iambic pentameter

The sibyl with her leaves of maddening verse,
Enchanted by her captivating curse;
Nor she nor I can say which one is worse:
    the silentness of sight
    or wind of words.

Cassandra sits with her among the leaves,
And Ariadne, weeping as she weaves;
Their sisterhood, this common curse of Eve's:
    the silentness of sight
    and wind of words.

Mother of God, whose face is ever bent
Toward thy Son's tree, assist me to repent,
That I may walk the way in which you went,
    who held in silent night
    both Wind and Word.
