Book review - "Roman History" by Cassius Dio

Dio always seems to rank below Tactitus, Plutarch and Seutonius whenever people discuss Roman historians, but he had his own niche and his work remains enjoyable to read. He had the advantage of being an eye witness to certain key periods, such as the reign of Commodus and Septimus Severus, winding up with Caracalla, Elegabulus and Alexander Severus.
