"In the reign of the same emperor [Augustus], there was a man also, remarkable for his extremely diminutive stature, being only two feet and a palm in height; his name was Conopas, and he was a great pet with Julia, the grand-daughter of Augustus. There was a female also, of the same size, Andromeda by name, a freed-woman of Julia Augusta."
