Vespasian wasn't exactly good looking either.
He had an unfortunate expression as well.
There's a story than when he arrived in Rome one of the dignitaries was adked why he hadn't greeted the emperor, and he said he was waiting for the emperor to finish emptying his bowels.
There was a hushed silence, it wasn't that long since Nero had been emperor and he treated dissenters very harshly.
Vespasian laughed, and everyone relaxed.
He was a very popular emperor, using his own money to build the colloseum on the site where Nero had had his winter palace.
