Answer:
"On the Sea" by John Keats and "By the Sea" by William Wordsworth
Explanation:
Both poems are from the same time period which helps with the language. Also, they have the same main object of discussion with the sea. Both also use religious language (so if you are not into that, you might try "Acquainted by the Night" by Robert Frost and "Sonnet 27" by Shakespeare; both use the sonnet format and both mention how the night comes upon them).
