Dio has long served as a source to writers treating topics of greater or less length in Roman history. He is now presented entire to the casual reader: his veracious narrative must ever continue to interest the historical student, who may correct him by others or others by him, the ecclesiastic, to whom is here offered so graphic a picture of the conditions surrounding early Christianity, and the literary man, who finds the limpid stream of Hellenic diction far from its source grow turbid and turgid in turning the mill wheels for this dealer in ογκος. Dio's faults are patent, but his excellencies, fortunately, are patent, too; and the world may rejoice that in an age of lust and bloodshed this serious-minded magistrate bethought him to record with religious exactness what he believed to be the truth respecting the Kingdom, the Republic, and the Empire of Rome even to his own day.
I desire in conclusion to express especial gratitude and appreciation for assistance and suggestions to Professor C.W.E. Miller of Johns Hopkins University, Professors J.H. Wright and A.A. Howard of Harvard University, and to Mr. A.T. Robinson of the Massachusetts Institute of Technology. Likewise I must acknowledge my obligations, in the elucidation of particularly vexed and corrupt passages, to the illuminative comments of Sturz, or Wagner, or Gros, or Boissée, or all combined. Additional thanks are due to many others who have helped or shall yet help to make Dio in English a success.
