By Diego De Saldana by Henry Wadsworth Longfellow

"Tristful" is an old English term that means sorrowful or mournful. It originates from the Latin word tristis, which translates to sad. Longfellow employs it to maintain the antiquated, noble tone of the Spanish original.

The speaker is focusing on a pair of eyes — the sad, sorrowful eyes of someone he has become infatuated with or deeply cares for. He never mentions their name; those eyes represent the entire person he loves.

The poem intentionally keeps this unnamed, but it most likely refers to love — specifically, the helpless, sleepless yearning that accompanies unrequited love. The term "betrayed" implies he arrived there without wanting to, almost deceived by the allure of those eyes.

He translated or adapted it from a Spanish poem attributed to Diego de Saldaña, a notable figure in the Iberian lyric tradition. Longfellow was an earnest scholar of European languages and dedicated a significant part of his career to translating poems like this one into English.

This is the poem's most intense psychological moment. When grief or longing runs deep, a person might actually push away comfort — the pain becomes so familiar that solace feels inappropriate or unwelcome. The speaker's soul has become so fretful and irritable that it turns away from the very thing that could provide relief.

"Cumber" is an archaic term for burden, trouble, or encumbrance. The phrase "Heart so full of care and cumber" conveys a heart burdened with worry and sorrow. Longfellow selected this word to give the poem an old-fashioned feel, as if it belongs to a different time.

The poem follows an ABBA rhyme scheme in every stanza, where the first and fourth lines rhyme with each other, while the second and third lines also rhyme. This type of "enclosed" rhyme scheme is typical in Spanish lyric poetry, contributing to the poem's compact, song-like feel.

The repetition comes straight from the Spanish cancioneiro tradition — a style of courtly lament that relies on refrains and repeated phrases to create emotional depth, similar to a folk song. This technique gives the poem an incantatory quality, as if the speaker is trapped in an endless loop.
