A Summer Day

By Henry Wadsworth Longfellow

    The sun is set; and in his latest beams         Yon little cloud of ashen gray and gold,         Slowly upon the amber air unrolled,         The falling mantle of the Prophet seems.     From the dim headlands many a lighthouse gleams,         The street-lamps of the ocean; and behold,         O'erhead the banners of the night unfold;         The day hath passed into the land of dreams.     O summer day beside the joyous sea!         O summer day so wonderful and white,         So full of gladness and so full of pain!     Forever and forever shalt thou be         To some the gravestone of a dead delight,         To some the landmark of a new domain.

Analysis & Notes:
This poem is a meditation on the fleeting nature of summer's joy, employing a formal structure that reinforces its themes. The sonnet-like pattern, with its consistent rhyme scheme and 14-line length, creates a sense of containment and finality, mirroring the poem's exploration of the transience of summer's beauty. The voice, a nostalgic and melancholic one, weaves together vivid imagery and rich sensory details, from the ashen gray and gold cloud to the street-lamps of the ocean and the banners of the night. The use of enjambment and caesura creates a sense of fluidity and longing, drawing the reader into the poem's contemplative atmosphere. The poem's tonal shift from the first stanza to the second is marked by a subtle but significant change in the speaker's tone. The first stanza's focus on the passing of the day and the falling mantle of the Prophet creates a sense of inevitability, while the second stanza's emphasis on the speaker's personal experience of summer's joys and pains introduces a more intimate and emotional tone. This shift is reinforced by the use of more direct address, with the speaker addressing the summer day directly, and the repetition of the word forever to emphasize the poem's themes of timelessness and loss. The poem's final line, To some the gravestone of a dead delight, offers a precise observation on the enduring power of summer's beauty, even as it acknowledges its transience and the pain that can accompany its passing.

Understanding the Sonnet

The sonnet is one of the most enduring and celebrated forms of poetry, known for its strict structure and profound themes. With a history spanning centuries, sonnets have been used to explore love, beauty, politics, and mortality, all within the confines of just 14 lines.


Sonnets are characterized by their precise form and rhyme scheme, which vary depending on the type of sonnet. Here’s a closer look:

  • Shakespearean (English) Sonnet: Composed of three quatrains followed by a final couplet, with a rhyme scheme of ABABCDCDEFEFGG. This form often builds a complex argument or narrative, culminating in a powerful closing statement.
  • Petrarchan (Italian) Sonnet: Divided into an octave (eight lines) and a sestet (six lines), with a typical rhyme scheme of ABBAABBA for the octave, followed by various patterns in the sestet such as CDECDE or CDCDCD. The octave usually presents a problem, with the sestet providing a resolution.
  • Meter: Sonnets are traditionally written in iambic pentameter, which gives the poem a rhythmic and melodic quality that enhances its emotional impact.

The sonnet’s enduring appeal lies in its ability to condense complex emotions and ideas into a small but potent package, making it a favorite form for poets seeking to explore profound themes with precision and elegance.
