| Quote #1 To that still roaring dell, of which I told; |
His friends enter the valley around mid-day, with the sunlight passing down directly through the branches. The forest is so dense that only some of the light makes it through to the ground.
| Quote #2 With some fair bark, perhaps, whose sails light up |
This poem has many images of objects being "lit up" by afternoon or evening light. Think of all the leaves and trees that are illuminated. The light on the sails contrasts with the "purple shadow" of the islands. The sails just catch the last bit of daylight.
| Quote #3 Ah! slowly sink |
The sunset forms the climax of the second stanza. All human activity in the poem ceases at this point as Charles is "struck" by the profound and transient beauty.
