in the poem, we understand that this day will not always be this way. They muse on the beauty of Autumn, before looking forward to the cold night ahead.

In the poem "A Day in Autumn" by R.S. Thomas, the poet presents a vivid and picturesque portrayal of an autumn day, capturing the beauty and fleeting nature of the season. The poem encourages readers to pause and appreciate the moment, as it suggests that such beauty is transient and will not last forever. Throughout the poem, Thomas employs various poetic techniques to convey his ideas and emotions. The poem begins with a declarative statement, "It will not always be like this," immediately setting the tone of transience and impermanence. This idea is reinforced by the description of the "windless" air and "last leaves"; the calmness of nature serves as a poignant reminder that this moment is unique and to be cherished. Thomas pays careful attention to the visual details of the scene, describing the leaves as "adding their decoration" to the "tree's shoulders," making use of personification to bring the image to life. Furthermore, the poet describes the leaves as "braiding the cuffs of the boughs with gold," which adds a sense of richness and beauty to the scene, highlighting the preciousness of the moment. In the middle of the poem, the focus shifts from the natural surroundings to the presence of a bird "preening." The image of the bird gazing at its reflection on the "lawn's mirror" emphasizes the importance of reflection and taking the time to appreciate one's surroundings. The poem's speaker then directly addresses the reader, urging them to "pause a minute" and let their "mind take its photograph" of the scene. This metaphor of mental photography suggests that our memories are a vital means of preserving these fleeting moments of beauty, even as the seasons change and time passes. The poem concludes by offering a purpose for capturing this mental image: "something to wear against the heart in the long cold." This metaphor not only implies that the cherished memory will provide comfort during darker times but also emphasizes the fleeting nature of beauty and life. Throughout the poem, R.S. Thomas employs a variety of poetic devices, including personification, imagery, and metaphor, to paint a vivid picture of the beauty of an autumn day. By urging readers to pause and take in these fleeting moments, the poem serves as a reminder of the transient nature of life and the importance of appreciating beauty while it lasts. Overall, "A Day in Autumn" is a poignant and evocative poem that encourages readers to engage with their surroundings and to treasure the fleeting beauty of the present moment.
