His vastness.

☞ The recurrence of the same letter in accented parts of words is also called alliteration. Anglo-Saxon poetry is characterized by alliterative meter of this sort. Later poets also employed it.
In a somer seson whan soft was the sonne,
I shope me in shroudes as I a shepe were.
P. Plowman.
