Yours truly, writing for Typekit:
Trajan is often employed when a stately, elegant presence is needed; however, its subtle contours and chisel-thin serifs weren’t designed for use at small sizes. Use Trajan big. Choose a similarly tasteful Renaissance-inspired text typeface for navigation, small headlines, and short bursts of copy. Minion (used for the three lines of text, above) is just such a text face.
