A metaphor is a comparison between two things which one would not necessarily associate. When examining Earle Birney's poem, "Vancouver Lights," many metaphors are present.
1."Quilt of lamps"- Here, the numerous lighthouses are compared to a quilt. Working in unison, like quilters, the lights serve their purpose (providing safety and comfort --much like a quilt).
2. "We the unique glowworms"- Here, the speaker compares himself (assumed given the poet's gender) and the reader (through his use of the pronoun "we") to glowworms.
3. "This twinkle we make in a corner of emptiness"- Here, the small light the speaker is able to cast is compared to the light of a star. While not direct, one normally associates a "twinkle" with a star.
4. "Our Phoebus himself is a bubble"- Here, Phoebus (the god of the sun) is compared to a bubble.
