Dionysius of Halicarnassus, Appian, Dio, John of Antioch, and others.

The _Excerpts Concerning Judgments_ are found in a Vatican manuscript
known as Codex Vaticanus Rescriptus Graecus, N. 73. Angelo Mai first
published the collection at Rome in 1826. They consist of many
narrative fragments extending over the field of Roman History from
early to late times, but fall into two parts: between these two parts
there is a gap of six or more pages. That the former set of fragments
is taken directly from Dio all scholars are ready to allow. In regard
to the latter set there have been, and perhaps still are, diverse
opinions. The trouble is that on the one hand these passages do not
end with the reign of Alexander Severus, where Dio manifestly ended
his history, but continue down to Constantine and (since the
manuscript has lost some sheets at the close) possibly much farther:
and on the other hand the style and diction differ considerably from
Dio's own. It was once the fashion to say that as many of the
fragments as come before the reign of Valerian (A.D. 253)[3] came from
Dio's composition, but that the remainder were written by an unknown
author. Now, however, it is generally agreed that all the excerpts of
the second set were the work of one man, whether John of Antioch, or
Peter Patricius, or some third individual. Still, though not direct
quotations from Dio, they are regarded as of value in filling out both
his account and that of Xiphilinus. The words are different, but the
facts remain undoubtedly true.

commonly allowed him.]

The _Excerpts Concerning Embassies_ are contained in somewhat less
than a dozen manuscripts, all of which prove to have sprung from a
Spanish archetype (since destroyed by fire) that Juan Paez de Castro
owned in the sixteenth century. Many of the copies were made by
Andreas Darmarius. The first publisher of these selections was Fulvio
Orsini (= Ursinus), who brought them out at Antwerp in 1582. As their
name indicates, they are accounts of embassies sent either by the
Romans to foreign tribes or by foreign tribes to the Romans. Some of
them are taken from Cassius Dio; hence their importance here.

Now it was the custom of the earlier editors to arrange the (early)
fragments of Dio according to the groups from which they were taken:
