Here lodge as in a sanctuary!
Come often to us, fear no wrong;
Sit near us on the bough!
We'll talk of sunshine and of song,
And summer days, when we were young;
Sweet childish days, that were as long
As twenty days are now.
II.
Stay near me--do not take thy flight!
A little longer stay in sight!
Much converse do I find in thee,
Historian of my infancy!
Float near me; do not yet depart!
Dead times revive in thee:
Thou bring'st, gay creature as thou art!
A solemn image to my heart,
This line conveys Wordworth’s loneliness. The picture he has given us throughout the poem is of an old man observing and “conversing” with a butterfly that has landed nearby. The narrator develops a false sense of companionship with the butterfly after “talking” to it. When the butterfly begins to leave the loneliness the narrator was feeling returns.
