A nobleman in England, France, and Germany, of a rank next below that of duke. Originally, the marquis was an officer whose duty was to guard the marches or frontiers of the kingdom. The office has ceased, and the name is now a mere title conferred by patent.
I remember being out here at the Sunset Marquis, and whoever knocked on the door, I would take that picture that I was writing and I would put that in the typewriter, so when I had the meeting, they would say: 'Oh, you're working on it right now?' John Sayles
He combines the manners of a Marquis with the morals of a Methodist. William Gilbert
