If there is a long written poem in only one stanza, then does that indicate, that it is only following one pattern?

What else does it indicate? If a poem is written in one whole stanza than is the poet who wrote that just talking about one thing wither in the past or present?

If a long written poem is presented in only one stanza, it does not necessarily indicate that it is only following one pattern. The structure of a poem, including the number of stanzas, does not dictate the number of patterns or themes explored within it. A single-stanza poem can still incorporate multiple patterns or themes through its use of language, imagery, rhythm, and other poetic devices.

The presence of a single stanza can, however, suggest a sense of cohesion or unity within the poem. It indicates that the poet has chosen not to divide the poem into separate sections or stanzas, but rather presents it as a continuous flow of thought or emotion.

As for whether the poet is talking about one thing in the past or present, the structure of the poem alone cannot determine that. The content and subject matter of the poem, along with its use of tense, imagery, and other contextual clues, will provide insight into the timeframe being addressed.

To better understand a poem, it is essential to delve into its language, imagery, tone, and other elements. Reading and analyzing the poem as a whole and looking for patterns, symbols, and shifts in meaning can help uncover the poet's intentions and the multiple layers of interpretation within the work.
