| Quote #1
Five years have past; five summers, with the length
The opening lines of the poem practically scream at you the importance of the past. The speaker repeats three times just how many years have gone by since he was last at the Wye: five. Five years.

The day is come when I again repose
Finally, after "five long winters," the speaker is able to repeat some of his earlier experiences. Or, at least, he's able to go over the same ground again. The experiences, as it turns out, are harder to duplicate.

These beauteous forms,
The "beauteous forms" describe the lovely view. Even during his "long absence" from the Wye river valley, the speaker says that the "forms" themselves have been present to him. They haven't just been like an empty description, like a "landscape to a blind man's eye."
