I haven't got a copy of Eupolemus right here, but I read the fragments of
his history for my dissertation, so I remember the problem you mention. I
believe the answer is quite simple. The fragments of Eupolemus' history
(this is not Second Maccabees BTW -- although some people think that
Eupolemus, the author, is identical with the Eupolemus who is mentioned at
one point in 2Macc) survive only in the form of extended quotations in the
work of a gentleman named Alexander Polyhistor. So the fragments of
Eupolemus are *entirely* in indirect discourse, with subject accusative,
preceded by the key words "Eupolemus says." =) I believe that some texts
of Eupolemus, like Holladay, don't include the connecting bits of Alexander
Polyhistor that provide those key words.
Hope this helps!
