In Swift's Gulliver's Travels, what special attributes does the Emperor of Lilliput possess which set him apart from the common folk?
The emperor of Lilliput is taller, by perhaps a centimeter or so, than anyone else in his court, and Gulliver says that the height difference is enough to impress a beholder. Likewise, he has "strong and masculine" features, a graceful and regal bearing, and superior posture and proportion. These seem to set him apart from the rabble, at least for Gulliver.
Besides this, Gulliver tells us that the emperor is almost twenty nine years old, has reigned for approximately seven years, and has been -- for the most part -- victorious and happy all the while. He is an excellent horseman, quite articulate, and very desirous, at least initially, of showing Gulliver hospitality and courtesy. He is later revealed to be somewhat less hospitable, especially when thwarted in his plans to defeat Blefuscu.
