16.  Gros-Boissee.—­French translation together with the Greek text and copious notes. (With new collation of the Vatican, Medicean, and Venetian codices, besides use of Parisinus A and Vesontinus; manuscripts of the Fragments, especially the Tours manuscript (concerning Virtues and Vices) have been carefully gone over.) Ten volumes.  Gros edited the first four; Boissee the last six.  Paris, 1845-1870.

17.  Dindorf.—­Teubner text.  Dindorf was the first to perceive the relation of the manuscripts and their respective values.  He used Herwerden’s new collation of the Vatican palimpsest containing Excerpts Concerning Judgments.  From making fuller notes and emendations he was prevented by untimely death.  Five volumes.  Leipzig, 1863-1865.

18.  Melber.—­Teubner text, being a new recension of Dindorf, with numerous additions.  To consist of five volumes.  Leipzig, from 1890.  The first two volumes, all that were available, have been used for this translation.

19.  Boissevain.—­The most modern, accurate, and artistic edition of Dio.  The editor is very conservative in the matter of manuscript tradition.  He personally read in Italy many of the MSS., and had the aid of numerous friends at home and abroad in collating MSS., besides the help of a few in the suggestion of new readings.  In the later portion of the text he makes a new division of books, and essays also to assign the early fragments to their respective books.  Three volumes.  Berlin, 1895, 1898, 1901.  Vol.  I, pp. 359 + cxxvi; Vol.  II, pp. 690 + xxxi; Vol.  III, pp. 800 + xviii.  The second volume contains two phototype facsimiles of pages of the Laurentian and Marcian MSS., and the third volume three similar specimens of the Codex Vaticanus.  In the appendix of the last volume are found, in the order named, the following aids to the study of Dio.

     1.  The entire epitome of Xiphilinus (Books 36-80).

     2.  Vatican Excerpts of Peter Patricius (Nos. 1-38), compared
     with Dio’s wording.

     3.  Vatican Excerpts of Peter Patricius (Nos. 156-191),
     containing that portion of the Historia Augusta which is
     subsequent to Dio’s narrative.

     4.  Excerpts by John of Antioch, taken from Dio.

     5.  The “Salmasian Excerpts.”

     6.  Some “Constantinian Excerpts,” compared with Dio.

     7.  The account of Dio given by Photius and by Suidas.

     8.  Table of Fragments.

Boissevain’s invaluable emendations and interpretations have been liberally used by the present translator, and some of his changes of arrangement have been accepted outright, others only indicated.
