Note 156 — WINDSOR FOREST.
Reading edition
So Dryden, Æneis, x. 156:
The winds their breath restrain, And the hushed waves lie flatted on the main.—Wakefield.
Pope's lines are compiled from the passage quoted by Wakefield and a couplet in the Court Prospect of Hopkins:
Unrolling waves steal softly to the shore, They know their sovereign and they fear to roar.
