By conflict, and their opposites, that trust

In lowliness—a mid-way tract there lies

Of thoughtful sentiment for every mind

Pregnant with good. Young, Middle-aged, and Old, 150

From century on to century, must have known

The emotion—nay, more fitly were it said—

The blest tranquillity that sunk so deep

Into my spirit, when I paced, enclosed

In Pisa’s Campo Santo,[80] the smooth floor 155

Of its Arcades paved with sepulchral slabs,[81]
