Describe Santiago's physical appearance.
Santiago is a very old man, but he has eyes like the sea.
The main physical description given of Santiago is that he is old in every way except for his eyes. His skin is browned from a lifetime of being outside in the sun. He has deep wrinkles on his face and the back of his neck. He has dark splotches on his face from what Hemingway says is "the benevolent skin cancer the sun brings." He is thin and gaunt.
Santiago has deep scars on his hands from using cord to catch heavy fish. They are old scars that are deep in his skin. There are no newer ones.
His eyes are the color of the sea. Hemingway says they are happy eyes that look undefeated.
