what is the metaphor involving the dutch sailors? how is it then connected to gatsby and the book? what is nick's viewpoint on this metaphor?

One of the concluding images of The Great Gatsby is Nick’s description of “the old island here that flowered once for Dutch sailors’ eyes—a fresh, green breast of the new world.” (180). This imagery reminds us of the predominance in the novel of fantasies insistently associated with men. The dutch sailor passage is the root of Nick’s fascination with Gatsby. Gatsby is an extravagant dreamer. Like the Dutch sailor in the passage, he embodies man’s capacity.
