Ploughed up a furrow with an iron staff
In the hard sand, and thrust a long lean chin
Outward and downward, and thrust out a foot,
And leaned to follow after. As he saw
His crooked knee go forward under him
And after it the long straight iron staff,
"The staff," he thought, "is Paolo: like that staff
And like that knee we walked between the sun,
And her unmerciful eyes"; and the old man,
Thinking of God, and how God ruled the world,
