Dio Cassius 67.14
 bAt this time the road leading from Sinuessa to Puteoli was paved with stone. And the same year Domitian slew, along with many others, Flavius Clemens the consul, although he was a cousin and had to wife Flavia Domitilla, who was also a relative of the emperor's.  The charge brought against them both was that of atheism, a charge on which many others who drifted into Jewish ways were condemned. Some of these were put to death, and the rest were at least deprived of their property.  Domitilla was merely banished to Pandateria. But Glabrio, who had been Trajan's colleague in the consulship, was put to death, having been accused of the same crimes as most of the others, and, in particular, of fighting as a gladiator with wild beasts. Indeed, his prowess in the arena was the chief cause of the emperor's anger against him, an anger prompted by jealousy. For in Glabrio's consulship Domitian had summoned him to his Alban estate to attend the festival called the Juvenalia and had imposed on him the task of killing a large lion; and Glabrio not only had escaped all injury but had despatched the lion with most accurate aim.
