The main themes are:
Greed is certainly a recurring theme as this is what motivated Midas to make his wish in the first place. The damaging effects are portrayed throughout with both husband and wife, in the end, being left alone to suffer the effects of wishing to possess a substance which ultimately
feeds no one.
Consequences of our actions is a prevalent theme as both Midas and his wife pay the price of not really taking the time to deliberate and think through what would follow if they chose one action over another.
Loneliness and solitude are all that is left for both characters by the end of the poem as a result of one selfish act. A life of solitude is chosen as soon as Midas is
granted his foolish and selfish wish.
