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.
Elpenor - Home of the Greek Word is a site built around a bilingual anthology of all periods of Greek literature, but there's more, including ancient greek lessons, a collection of texts by non-Greeks about Greece, a gallery of Orthodox Christ icons and an online resource-guide on Byzantium.
