Not found, though a passage from Appian concerning the Gallic king Brennus was preserved in the Embassies of Constantine Porphyrogenitus, extracts from which were `first collected in a slovenly manner by Fulvio Orsini (Ursinus) and published in Antwerp in 1580 [in fact 1582]': Appian's Roman HistoryI, trans. H. White (Loeb, 1912), viii, 106-9. Most of this paragraph was new to the 1587 edition, perhaps increasing the likelihood of Harrison's having consulted Orsini's edition of Constantine.
