From the back:

Imperial Rome — centre of the world — throbbing with the white heat of violence, bloodshed and uninhibited sexuality…
Bought as an actor, kidnapped by pirates, sold as a gladiator, young Cleon’s beauty and flagrant masculinity made every woman – harlots and Vestal Virgins alike – desire him.
And passion drives Cleon to help destroy a Caesar who combined the vices of his predecessors with his own special perversions — the Emperor Nero…

Frank Frazetta also did a cover for this book.
