How does Dana Gioia use imagery in The Litany?

The first stanza is filled with negative imagery, as the three participants involved in the event, the flower, the moth, and the spider, become assorted characters of death and blight in one line and mixed ready to begin the morning right in another. In these two lines, Frost contrasts the rightness of nature's cycle with the recognition that death and blight are a part of that cycle. In the next line, the three characters become the ingredients of a witches' broth, suggesting a design of darkness to appall. Here, Frost implies that the creator of this cycle may have had a sinister intent.
