Bulfinch's Mythology , By Thomas Bulfinch. Published by several publishing houses. One of the best collections of myths and fables around. The author draws examples from classical literature to illustrate the myths. Not entirely complete, but very good for the individual seeking a guise to the more common myths.
Many versions have all three volumes bound into one.
Be sure to look for an unabridged copy. These are my two all time favorite books. The characters find themselves in several odd situations. Many of the stories revolve around the character Doc Ricketts, based on Steinbeck's good friend Ed Ricketts. Sweet Thursday is the sequel to Cannery Row .
