Question

What is the relationship between Byron and Childe Harold?

Answer 1

"In creating Childe Harold, Byron improved the quality of his own life and made an image that was better than he; Byron calls himself nothing and says Childe Harold is more. In Lines 52 through 54, Byron and Childe Harold are "mixed" and "blended" together. This relationship carries through the poem; whatever Byron says of Childe Harold, he also says of himself."

This shows that Byron told stories of himself through Childe Harold and his character became a reflection of him.

Answer 2

In the first two cantos, Byron wrote of Childe Harold without asserting his own identity. Canto III was published in 1816. By this time, Byron's marriage had ended, and the self-imposed exile spoken of in the poem applied to the poet as well. In Canto III, Childe Harold and Byron were separate characters but shared many traits. Byron's readers automatically identified the hero with the poet.
