The short syntactical lexicon (IIερὶ Συντάξεως) published in Bekker's Anecdota Graeca (vol. i. pp. 117-180) contains nearly 140 brief citations from Dio, nearly all of which are assigned to their several books, though unfortunately many of the numbers have been corrupted. On the basis of these citations, compared with the epitomes, von Gutschmid and Boissevain independently attempted to determine the points of division between the lost books of Dio, and reached essentially the same results. Yet in several places the evidence is insufficient to constitute more than a reasonable probability.
The lexicon of Suidas, the Etymologicum Magnum, and a few other compilations of like character are also useful in affording occasional citations from Dio, often by book-number.
