Eh, I don't really make that association, although I tend to read equites as equites and what books I read on Roman history call them equites so *shrug*.
That said, I've been reading Romance of the Three Kingdoms recently and it's a tidge jarring to see characters being appointed titles like "Marquis" and the hullaballoo many of the characters make over, say, Cao Cao assuming the title of Duke is intriguing. Obviously the British hierarchical system of Baron-Viscount-Earl-Marquess-Duke-Prince-King-[Emperor] didn't exist in either 3rd/4th c. China nor under the Mings, so it'd be interesting to me to learn what the actual titles were and what they actually meant in a larger socio-political context.
