Classical Mythology
- Bullfinch's Mythology
Contains the complete text of Thomas Bullfinch's Age of Fable, Age of Chivalry, and Legends of Charlemagne—taken together, one of the classic compendiums of Roman and Greek mythology and Arthurian legend and romance. Tales are linked to each other within the site for quick cross-referencing. - Encyclopedia Mythica
Almost 6,500 short entries, featuring mythologies from every continent on the planet. Fully searchable, with copious cross-links to Bullfinch where appropriate. An excellent starting place for mythological research. - Classical Myth: The Ancient Sources
Only contains information about the major Olympians (for now?), but has links to the original sources for stories about each god/goddess at The Perseus Project, which can be pretty daunting to search through on your own. A good resource if you're doing heavy research about the Olympians. - The Mythman's Myth Mania
Nick Pontikis' lighthearted look at Greek mythology. Features his own retelling of myths in the Myth of the Month, as well as an extensive Homework Help section. - Dictionary of Greek and Roman Biography and Mythology
Smith's Dictionary of Greek and Roman Biography and Mythology is a 3,700-page compendium of 19th century classical scholarship. The Dictionary covers a dazzling array of historical characters, authors, gods and heroes in great detail and depth. (Online at The Ancient Library, a new and growing resource.)
