What does the Henry C. Calhoun poem mean in "Spoon River Anthology"?A short summary

Henry C. Calhoun is the son of Granville Calhoun, who
speaks in the previous poem.

Granville had been the County
Judge for many years, and wanted to be elected one more time so that he could "round out
a service / Of thirty years."  His friends, however, betrayed him, and "a new man" was
elected.  Granville was "seized" with "a spirit of revenge," with which he infected his
four sons.

Henry revenged his father's disappointment by
rising to "the highest place in Spoon River."  It is not clear from the poem exactly
what this position is; the poem only says that Henry sought "wealth and...power" with a
"furious energy."

Although the poem does not specify, it
seems that Henry's rise to power did not bring happiness with it.   He describes revenge
as "an envenomed [poisoned] robe," and advises us to avoid
it.

In giving his advice, Henry uses allusions to classic
Greek mythology.  He says that his father sent him along "the path that leads to the
grove of the Furies."  The Furies were three goddesses who punished mortals for their
crimes.

He also refers to the Fates, three goddesses who
controlled human destiny.  He says that if you see them weaving, and you see the "thread
of revenge," you should cut it away, "lest your sons, / And the children of them and
their children / Wear the envenomed robe."
