I read a poem called "winter evening" by Archibald lampman and Im supposed to connect this poem to the question of how this poem is about nature. How can I support this? Any notes or points can help :)

Also im allowed to interpret this poem by analyzing any image patterns and how they contribute to theme. I dont think nature relates to this so maybe this is a better topic?

Your second option sounds much more do-able! I don't see "nature" in the poem at all. Lots of images, though!

could you help me to understand the theme of the poem? Im not able to understand what it is which is why I cant move on to the imagery part

You'll find it very helpful as you continue to deal with literature and interpreting such.
Use the left column as the table of contents. Scroll down and read about Theme. Let me know what you think.

PS -- Another way to think about a theme is this: What's the secret (underlying) message the author wants his/her readers to understand?

Keep in mind that this may be a very modern way to use the structure of the sonnet.

14 lines
3 quatrains, plus a couplet
Read up on sonnets, too, so you can decide if you want to include that.

To demonstrate that the poem "Winter Evening" by Archibald Lampman is about nature, you can consider the following points:

1. Imagery: Analyze the vivid descriptions of natural elements used throughout the poem, such as "purple-black, heavy-sweet," "streaks of clear, fine beryl" and "the long wood-fringes" among others. These imageries invoke the reader's senses, allowing them to visualize the beauty of nature during a winter evening.

2. Personification: Observe how nature is personified in the poem. Lampman attributes human qualities to nature, such as "windows of the sky" or "Nature's waiting-room," which portrays nature as a living, breathing presence. Such personification allows the reader to develop a deeper connection with nature.

3. Symbolism: Explore any symbols that could represent nature in the poem. For example, the "fir-tree dark and still" could symbolize the enduring and tranquil nature of the winter landscape. Additionally, the "steppe of snow" may symbolize the purity and untouched beauty of the natural world.

4. Themes: Consider the overarching themes of the poem. If the themes revolve around the beauty, tranquility, or grandeur of the natural world, it further supports the notion that the poem is about nature.

5. Context and Biographical Information: Research the poet's background, interests, or other works to gain insights into their inclination towards nature-centric poetry. Examining the cultural or historical context in which the poem was written may also provide additional support for the connection to nature.

By considering these points and delving deeper into the poem's imagery, personification, symbolism, themes, as well as the context surrounding the poet and the time period, you can effectively support the idea that the poem "Winter Evening" by Archibald Lampman is about nature.
