The internet is an extraordinary tool for finding information quickly and conveniently. However, much of that information is valueless, since just about anyone can "publish" on-line just about anything they want. The first rule, then, is not to accept anything you read on the web just because it's there. Verify statements on your own by referring to materials you know are (on the whole) reliable: our textbook, mythological or classical dictionaries you find in our library, and so on. Don't let the ease of using the internet keep you from getting acquainted with our library's collection, which is much more comprehensive than anything you will find on the web (not to mention the question of reliability). I have put on reserve at the Reserve Book Room (RBR) a number of useful print resources which I encourage you to browse as soon as your research becomes more serious than mere "web-surfing."
The second rule is to respect the authors' and publishers' copyright. Nearly everything you find through the links listed below is copyrighted, which means you cannot "re-publish" content (for example, by posting a copyrighted image on your own web-site) or generally use it for any non-academic purpose. Also, the source of text you quote or paraphrase must be credited just as you would credit text you find in a book. Not to do so is to commit plagiarism. (The Perseus Project has an informative page on copyright, including an example of web-citation.)
The companion website to our textbook, Classical Mythology Online, is excellent, and conveniently organized by chapters of Morford & Lenardon. Chapter summaries and quizzes should be very useful for review, while interesting details, connections, and images can be explored with the help of the supplemental commentaries, chapter-specific links and bibliographies, and suggestions for further study ("Activities"). There are good glossaries of names and terms for quick look-ups, and a few clear maps. Under "On Line Archive" there is a small collection of literary works on mythological subjects, mostly modern.
Prof. Laurel Bowman's Classical Myth: The Ancient Sources website (University of Victoria) includes links to major texts for episodes in the myths of the Olympian gods, a fine set of accompanying images, a good timeline of Greek history and literature, and a handy illustrated list of gods' attributes in art and myth (for example, Zeus's thunderbolt).
Carlos Panada's Greek Mythology Link is incredibly comprehensive: many beautiful images, searchable summaries of mythological figures and events great and small, handy family trees of mythological figures, excellent maps and so on. But this resource, which has no academic affiliation or independent certification, needs to be used with care. The summaries, while quite complete, also (necessarily) "iron out" many important details and variants, and on the whole give no sense of the account's relationship with the sources. Furthermore, I find the interpretive comments (see esp. "On the myths") idiosyncratic, and certainly not helpful for this course. Still, nothing else on the web equals this site's range and depth, and a little surfing is likely to turn up some fascinating connections you would not have made otherwise.
The purview of Ancient Greek (Hellenic) Sites on the World-Wide Web is much greater than mythology. It's a good place to start a wider exploration of potentially relevant sites of all kinds.
The glossaries of Classical Mythology Online (above, general sites) are probably the first place to look, if you need only a brief summary, without great detail. Links to family trees. Good, clean family trees of major figures can be found at Prof. Ruth Webb's website for Classics 212 (Classical Mythology) at Princeton University. Carlos Panada's The Greek Mythology Link (above: "General Mythology Websites") has many more, and more elaborate ones, following a number of its biographical entries.
The central narratives associated with each of the Olympian Gods are grouped together in Laura Bowman's Classical Myth web-page mentioned above.
The most powerful on-line tool, however, is the The Perseus Encyclopedia, which can be searched for references to any mythological character. Episodes in that figure's mythology will be listed with links to the relevant portions of "Apollodorus" (see below, "texts"), or the second-century AD "tour-guide" by Pausanias. The linked text of "Apollodorus" (or Pausanias) will itself contain links to many other versions of the myths, taking you back perhaps to Homer and Hesiod or forward to Ovid's Metamorphoses. This extremely useful resource may be used as an on-line mythological dictionary, or as an powerful research tool with which to pursue significant mythological variants. However, you may have to experiment a little with spelling: "Typhoeus," for example, will be found under "Typhon (2)." (Morford & Lenardon's index gives variant names.)
The Perseus Digital Library is always a bit slow. If it seems inordinately so, you might try the mirror site in the UK.
The complete text of the ancient mythological Library once ascribed to "Apollodorus" (first or second century AD) is available on-line through the Perseus Project. This is an extremely useful source for Greek mythology, since its compendious (if cursory) survey of the myths told in the enormous mass of Classical literature still available at its time of writing fills many gaps left by the individual works that happen to survive today. (For example, the events of the 10-year Trojan War outside the brief segment told in the Iliad.) Sir James George Frazer's commentary (included by Perseus) is very outdated, but will often cite variant versions in surviving texts. Go to a specific chapter, or, if you only know a name, enter the text of "Apollodorus" (= Apollod.) via the Perseus Encycopedia (above, "names and stories").
The Perseus Digital Library also offers complete on-line texts of a great deal of Greek and Roman literature relevant to mythology, including (especially) a number quite central to this course, such as Hesiod's Theogony and Works and Days, Sophocles' Oedipus the King, Euripides' Bacchae and Medea. (See the list of authors and titles here.) Particularly important is the Metamorphoses of the Roman poet Ovid, available here unfortunately in a rather antiquated translation.
The Perseus Digital Library, Classics Collection (editor-in-chief Gregory Crane, Tufts University), includes an enormous, searchable image database, including over 1,500 vases, 1,800 sculptures, 1,200 coins, and hundreds of buildings from over 100 ancient sites. If you're looking for a particular item, start at the Art & Archaeology Catalogs (scroll down to "Secondary Sources" and go from there, depending on the type of object you're after.) Alternatively, if you're looking for the subject depicted (including mythological divinities and heroes), start at the Art & Archaeology Browser and work your way in. (For example, for vases showing Theseus, click successively on "vases," "keyword," "legendary people," "Theseus." There are 100 listed!)
Other less comprehensive, but interesting collections of images include:
Prof. Thomas Martin (College of the Holy Cross) provides a handy on-line survey of Greek history, hosted by the Perseus Project. Among the relevant sections of this work to our course are those on Greek religion, Greek tragedy, and various sections on Greek women ("Inequality and Women in the City-State," "Women and the Household" (and the sections immediately following), and "Property, Social Freedom, and Athenian Women."
Prof. Marilyn Katz (Wesleyan University) well highlights the importance of myth (and its problems) for reconstructing the history of Greek women in her recent essay, "Daughters of Demeter," published in Becoming Visible: Women in European History, 3rd edition, edited by Renate Bridenthal, Susan Mosher Stuard and Mary E. Wiesner (Boston: Houghton, Mifflin and Co., 1998), pp. 47-75.
For Bronze Age archaeology, whose connections with Greek mythology are evident but controversial, see Prof. Jeremy Rutter's superb, well-illustrated on-line course in The Prehistoric Archaeology of the Aegean (Dartmouth College). Especially relevant to debates about the historical basis of Greek mythology is lesson 27: "Troy VII and the Historicity of the Trojan War." If you're interested in Mycenae and the Mycenaeans, check out at least lessons 16, 19, and 25; for Crete and Minoan Civilization, look at lessons 12, 14, and 18 in particular.
Morford & Lenardon has a number a good maps; see the map index on p. xii of the table of contents. Others, including maps of Theseus' journey to Athens or of Jason's travels, appear on the associated website. For the Homeric poems, there are good maps following p. 67 of both Fagles' Iliad and his Odyssey.
On-line, simple maps of the main sites in Greek mythology can be found at Mark Woon's Classical Mythology by Geography pages at Princeton University (try this one too).
For detail and extent of annotation, however, you can't beat the maps in Carlos Panada's Mythology Link (see above, under "General mythology websites"). Go to his map of Greece and Western Asia Minor, and if relevant, move on to his linked maps of the major Achaean and Trojan contingents in the Trojan War, of the "Returns," and the area around Troy ("Troad").
