Humanities and the Liberal Arts is the personal website of former Middlebury classics professor William Harris who passed away in 2009. In his retirement he crafted a wonderful site full of essays, music, sculpture, poetry and his thoughts on anything from education to technology. But the heart of the website for me is, unsurprisingly, his essays on ancient Latin and Greek literature some of whom are book-length works. Here are a few examples: Purple color in Homer, complete fragments of Heraclitus, how to read Homer and Vergil, a discussion of a recently unearthed poem by Sappho, Plato and mathematics, Propertius' war poems, and finally, especially close to my heart, his commentaries on the poetry of Catullus, for example on Ipsithilla, Odi et amo, Attis poem as dramatic dance performance and a couple of very dirty poems (even by Catullus' standard). That's just a taste of the riches found on Harris' site, which has been around nearly as long as the world wide web has existed.
Something Rich and Strange. Publius Vergilius Maro was certainly a historical figure, but an unusual amount of fantastic trappings seem to have accumulated around him. Sometimes known more as mythical figure than as a poet of myths, he has seen modern revisions both fabulous(previously discussed) and absurd.
