Answer:
The excerpted lines from Petrarch's "Sonnet 292" contain an example of metaphor. The light is being compared to something that is loved, implying that it brought joy and happiness to the speaker.
Step-by-step explanation:
The lines "Left here without the light I loved so much" use a metaphor to compare the absence of something (presumably a person or a source of happiness) to the absence of light. The metaphor implies that the person or thing that is absent was like a source of light, providing guidance, clarity, and joy to the speaker's life. The use of this metaphor helps to emphasize the emotional impact of the absence on the speaker, highlighting the depth of their grief and self-contempt.
