Grave is the Master's look; his forehead wears
Thick rows of wrinkles, prints of worrying cares:
Uneasy lies the heads of all that rule,
His worst of all whose kingdom is a school.
Supreme he sits; before the awful frown
That binds his brows the boldest eye goes down;
Not more submissive Israel heard and saw
At Sinai's foot the Giver of the Law.
