Well, I need to conclude my blog with some final thoughts. At the start of this blog I did not know very much about Ancient Greek Religion, so what have I learnt...?
I believe I understand more about why Poseidon behaves the way he does, namely that he is god of the sea and so needs to represent the characteristics of the sea. The reason Poseidon's character is as it is is because he needs to fulfil the requirements of a god of the sea, so he is bitter and quick-tempered. The Ancient Greeks tried to explain his personality by having Poseidon lose out to his brother Zeus as head of the gods of Ancient Greece. I have tried to explain this using the diagram below. This is the advantage of assessing some work via blogs as it enables more versatility in putting across my opinion.
This investigation into the role of Poseidon has led me to believe that the gods of Ancient Greece were created for aetiological purposes. The gods were created to explain the behaviour of nature. Poseidon, my vehicle for this module, the bitter god of the sea, has demonstrated that his role had to be as it was. A god of the sea would have to have a similar personality to reflect the power, unpredictability and capacity for destruction, which the sea would seem to have from the viewpoint of a person where much of the world was a mystery.
