"The Terrible Vengeance" is a rather tedious fairy tale with an incestuous theme, while "The Portrait" bears some likeness to a certain, later work by Oscar Wilde. Though the idea is interesting, Gogol, as in several other stories, just doesn't know when to let go. The story "Ivan Fyodorovich Shponka and His Aunt" contains lively humor and many colorful characters. I enjoyed it the most of all, but it was only the beginning of a larger work, which unfortunately seems never to have been completed.
Some analysts (see the Introduction by the translator)have read into Gogol's work pre-revolutionary predictions of violent change or a rising up of the lower classes. I think such an idea is far-fetched. Similarly, while it is true that Gogol's tales and stories do contain struggles between good and evil, the same can be said of an enormous number of folk tales, religious works, and literary pieces by writers in every language. It is interesting to read Gogol's work to widen your knowledge of Russian and world literature. That is a source of satisfaction, but perhaps not enough. Several of the stories are good, but they don't measure up to his longer works---"Dead Souls" and "The Government Inspector". I would read them first, before this lesser book.
