Blog title (header) – Grecian Empire Regular (transparent PNG file, distressed a little with Photoshop)
Tagline – Georgia, Bitstream Charter, Serif
Navbar – Helvetica Neue, Arial, Helvetica, Nimbus Sans L, sans-serif
Entry Titles – Berylium Bold by Larabie Fonts (@font-face kit generated at FontSquirrel.com). This isn’t exactly the font I wanted here, but it’s pretty close.
Post Entries – Times New Roman, Times, serif. Kind of a boring choice, but unlike a lot of fonts, Times New Roman contains all the glyphs for ancient Greek. And its thick stroke size makes it readable, to boot. (I’ve added a little extra space between words in the CSS.)
Greek Characters (large) – Theano Didot Regular. A beautiful font for ancient Greek, but not as readable as Times New Roman at smaller font sizes. (See my page on Greek fonts for more details.)
Blog title (footer) – Caesar Dressing (embedded from Google Fonts)
