As when a prowling wolf,
Whom hunger drives to seek new haunt for prey,
Watching where shepherds pen their flocks at eve,
In hurdled cotes amid the field secure,
Leaps o'er the fence with ease into the fold;
Or as a thief, bent to unhoard the cash
Of some rich burgher, whose substantial doors,
Cross-barred and bolted fast, fear no assault,
In at the window climbs, or o'er the tiles;
So clomb this first grand Thief into God's fold:
So since into his Church lewd hirelings climb.
Thence up he flew, and on the Tree of Life,
The middle tree and highest there that grew,
Sat like a cormorant; yet not true life
Thereby regained, but say devising death
To them who lived; nor on the virtue thought
Of that life-giving plant, but only used
For prospect what, well used, had been the pledge
Of immortality.
