To solve these knots I must call down from high
Some heavenly help, feather with angels wing
The sluggish arrow. If it will not flie,
Sent out from bow stiff-bent with even string,
Let angels on their backs it thither bring
Where your free mind appointed had before,
And then hold on, till in your travelling
You be well wearied, finding ever more
Free passage for their flight, and what they flying bore.
