What are some examples of literary realism in the poem, "George Gray" by Edgar lee masters?

In the poem "George Gray" you can see an opposition to romanticism.

Explanation:

If we analyze it, realism was an opposition to romanticism. It focused more on reality, scenes from everyday life and provided many details of it. Anything related to romanticism was rejected by this movement.

In this poem we have some examples of that.

For example:

When the author uses the phrase "For love was offered me and I shrank from its disillusionment", he wants to get away from love because he has suffered, this is an opposition to romanticism. Another example is when the author provides details of his boat: "A boat with a furled sail at rest in a harbor." This is a description of something real with details and specific.
