In The tempest, knowledge and power were the two main themes. The author portrayed the character of Prospero and equipped with both knowledge and power. However, he did not use his knowledge at the right place. He was the king of the Milan, but due to his over indulgence in learning magical powers from his books, he neglected his own kingdom and defeated by his brother Antonio. Prospero then travelled to a secluded island where he subdued Sycorax, the witch and treated her badly. This showed the Prospero’s colonized nature that led him to take full control of the island and push back the actual inhabitants of the island. Caliban, the Sycorax’s son was also mistreated by Prospero. Miranda, the daughter of Prospero, like his father, believed that Caliban was a monster and he cannot be taught to become a decent man. Both father and daughter showed their knowledge and power to control the island and Caliban was their servant (Themes in Shakespeare’s The Tempest).
Due to being more knowledgeable, Prospero used the words like elemental, ignorance and darkness to refer to the Caliban. Prospero thought that he was a colonizer and he was ruling the island to make it a civilized place. Here he used his knowledge as his power, which he lost in Milan. He even tried to civilize and educate Caliban, which did not get any success, though Caliban learnt few words that he used against Prospero for abusing him. The knowledge here was described as the medium of controlling and dominating the colonized (Themes in Shakespeare’s The Tempest).
On the other hand, if we talk about the power, we can say that Antonio had the power of the kingdom of Milan because he did not waste his time to overtake the kingdom when Prospero was busy in gaining knowledge. However, when Antonio and other travellers reached the island after the storm created by Prospero, the power of Antonio failed. The island was totally in control of Prospero hence Prospero was the most powerful man there. Once Antonio tried to kill Prospero with the help of Sebastian and the King of Naples, but he failed and asked Prospero to forgive him. However, in the end Prospero forgave every one of them and gained the power of Milan (Themes in Shakespeare’s The Tempest).
