I Gave You Immortality most closely resembles Shores. Both appeared in the collection Dain Do Eimhir agus Dain Eile / Poems to Eimhir and Other Poems (1943). Each is, in a sense, a love poem. Shores is positive in tone. It talks about the strength of love. I Gave You Immortality is more complex. The feelings it portrays are a mix of love and sorrow, gratitude and pain.
In these, as in Hallaig, MacLean presents emotions, thoughts, memories and his verse as things that can transcend the passing of time.
By presenting the poem as a memorial, I Gave You Immortality can be linked to Hallaig, which remembers real people and their way of life. These poems build on the bardic tradition of keeping memories of people alive.
While most of the poems in the set are specific about place, I Gave You Immortality does not record actual locations. In this way it can possibly be seen as more obviously universal in its message.
