This does not speak to me of an author assembling his material re-modelling it extensively and producing an integrated and nuanced text; rather it smacks of someone reading a passage making notes according to that source’s division of matters, Spring-Winter in the case of Hieronymus, I am unclear on the Sicilian source but March to March, the consular year for the annalistic Roman material. If this were the method, and I concede there is no real evidence for or against, then Diodorus would tend to preserve the scene changes of his source; it might prove fruitful to examine how the scene does shift from Europe to Asia in the Hieronymean material only I can’t see how one could decide whether the pattern originated with Diodoros or his source, the more so if one considers him to be significantly revising his sources’ structure.
He most assuredly followed a "central" source. That source, in my view, being an intermediary rather than Hieronymus directly. The constant dismissing of Antigonus as arrogant, harsh and a rebel against the kings cannot have come from a writer patronised by the house whose founder Antigonus was; especially when contrasted with the near hagiographic approach to the arch enemy Ptolemy (and Seleucus for that matter) . He will have continued to follow this source into books 19 and 20 but here another intrudes and that source was focused upon Agathocles. The most likely candidate is Duris although it could never be ruled out that the central intermediary source also contained this. The detail - and there are long involved stretches of "Agathoclean" history with a host of named actors - speaks more to a dedicated source though.

18.42.1: Their leader was Hieronymus, who has written the history of the Successors.
18.50.4: With these plans in mind he summoned Hieronymus the historian, a friend and fellow citizen of Eumenes of Cardia, who had taken refuge in the stronghold called Nora. After endeavouring to attach Hieronymus to himself by great gifts, he sent him as an envoy to Eumenes,
19.44.3: Among the wounded there was also brought in as a captive the historian Hieronymus of Cardia, who hitherto always had been held in honour by Eumenes, but after Eumenes' death enjoyed the favour and confidence of Antigonus.
19.100.1: In charge of this he placed Hieronymus, the writer of the history, and instructed him to prepare boats, collect all the asphalt, and bring it together in a certain place.
I don't know that I'd describe those as "apologetic". Yes, they are somewhat longer that the note of Marsayas' brilliant fighting beside Demetrius, but not greatly. As for the missions, the first is to seek a rapprochement with Eumenes and the quote above it the extent of Hieronymus' role. The second, the asphalt mining, is different. Bosworth has argued that the excursus on the Nabataean Arabs and the intrinsic difficulties in subduing these disappearing nomads that appears in book 19 is Hieronymus' own excusatory manifesto for his failure. He may well be right. Still does not nail a direct usage of Hieronymus though.
agesilaos wrote:Arguments based on the supposed biases of non-extant authors are never going to be strong; I suspect that the low opinion held of Diodoros would tend to make the thought of his wading through the mammoth and inelegant work of Hieronymos anathema. Yet he seems to have used Polybios’ forty books and, I would argue, the fifty-eight of Theopompos’ Philippika. Certainty is impossible as per usual.
I would think he clearly did read most, and probably all, of Polybius. Whilst one can never be certain, it's likely there was no other way in Diodorus' day.The polemics against Timaeus clearly come from this source and from memory by their presentation (13.90.6-7 and 21.17.1-3 for example). Similarly, one can never rule out that he read Hieronymus though I'd stick with my caveats for direct use above as I think it wildly unlikely that Diodorus searched for hagiographic tid-bits from a pro-Ptolemaic (and Seleucid) source to insert into his narrative.
I agree it is very unwise to proceed on the supposed biases of non-extant sources. In the case of Hieronymus, though, those biases (or the major one) were well known in antiquity:
Paus.1.13.9:
The account, how ever, given by Hieronymus the Cardian is different, for a man who associates with royalty cannot help being a partial historian. If Philistus was justified in suppressing the most wicked deeds of Dionysius, because he expected his return to Syracuse, surely Hieronymus may be fully forgiven for writing to please Antigonus.
Now, it might be said that this was simply Pausanias' view. Elsewhere, though, he makes plain that this was a widely held view in antiquity:
Paus.1.9.2:
The next part of the story is incredible to me, but Hieronymus the Cardian relates that he destroyed the tombs and cast out the bones of the dead. But this Hieronymus has a reputation generally of being biased against all the kings except Antigonus, and of being unfairly partial towards him.
Note the the reputation was generally known. It is hard to conceive that Hieronymus could so publicly trash Gonatas' grandad's reputation so.
I'd also argue that it's unwise to work from the notion of a supposed narrative structure of said sources. We simply do not know when and how those sources altered focus; the hermeneutic circles so beloved of Taphoi are always hovering. Whilst it might be more likely that these were in his source, there are always those wonderful little excursions of Diodorus - not always introduced as such to be sure - rounded off with the formulaic "now that we have said enough on XYZ, let us return to our place in our narrative" or some such to keep one guessing. The Themsitocles eulogy, to me, looms largely as Diodorus' own comment (11.58.4-59.4). Also the great long and moralising diversion into Charondas and Zaleucus(12.11.3 - 21.3) is surely fashioned by Diodorus. This addresses the other of his great themes: the law (or "good laws") and respect for it. Whilst Diodorus' source may have shared the same fetish, I get the distinct impression that the length and detail are the result of Diodorus' own investigations and embellishment.
