The Internet Encyclopedia of Philosophy is an excellent resource for matters philosophical. There you can be enlightened on such diverse subjects as paradoxes existential or logical, Greek or American philosophers obscure to the wider world, philosophers whose names have resounded through the ages, both well-attested and possibly mythical, Buddhist thought and Western mysticism and definitions of thorny and difficult concepts. And that's just a small sampling of the letter P section. All articles are written by specialists on the subject and the editors of the IEP are all academic philosophers. The encyclopedia is far from complete, so if you think you can help out, they have a list of their 100 most desired articles.

Theoi Greek Mythology is an internet encyclopedia with over 1500 pages on various characters from classical myth, covering everything from famous gods and goddesses to obscure nymphs, titans and monsters. If the confusing familial relations of the Greek gods vex you, there are 10 different family trees to help you make sense of it all. There's also an extensive library of ancient works concerning classical mythology and a bibliography should you long for more to read. Last but not least, Theoi has a gallery of over 1200 artworks from antiquity, which I have been happily browsing for a good while.
