multos circa unam rem ambitus fecerim si quae de Marcelli morte variant auctores omnia exsequi velim.  ut omittam alios, Coelius triplicem gestae rei <mem>oriam1 edit, unam traditam fama, alteram scriptam laudationem2 filii qui rei gestae interfuerit, tertiam quam ipse pro inquisita ac sibi comperta adfert.  ceterum ita fama variat ut tamen plerique loci speculandi causa castris egressum, omnes insidiis circumventum tradant.

F 1 Livy, History of Rome
I would be making many twists and turns around a single matter, if I wished to go through everything in which writers differ concerning the death of Marcellus.  Not to mention others, Coelius [L. Coelius Antipater, Roman historian at end of 2nd cent. BC; FRHist 15] provides a threefold record of the event: one as transmitted by tradition, a second the eulogy, written down, by the son, who was present at the event, a third that he himself adds as investigated and discovered by him.  In any case, the reports vary in such a way that, still, most writers relate that he [Marcellus] left the camp to explore the locality and all that he was overwhelmed by an ambush.
