Vulcan in the 'American Gods' is presented as a complex character. He has a strong connection to his mythological roots of fire and metalworking. His appearance and actions are probably influenced by the traditional ideas of Vulcan from Roman mythology. However, in the novel, he is also a being that is in a state of flux. He is losing his influence as the world changes and people turn away from the old beliefs. He is shown as a proud god, yet one that is facing an uncertain future as the new gods rise to prominence. His portrayal helps to drive home the overarching theme of the struggle between the old and new gods in the story.
