Thomas Bulfinch 
Bulfinch’s Mythology 

Bulfinch’s Mythology is a thorough overview of three major groups of mythology, and has long been cited as one of its definitive reference texts.It is broken up into three sections, covering classical mythology (primarily Greek and Roman, though Bulfinch also touches on eastern, Norse, and druidic myth), the legends of King Arthur, and the romances of the middle ages. It is both thorough and detailed, but is presented in a way that makes it accessible to all readers.
