who does Livy mean by "maiores eorum" here?
Hannibal is giving a motivational speech in A.U.C. XXI about how the Alps are actually not that bad:
> Alpes quidem habitari, coli, gignere atque alere animantes; pervias paucis esse, esse et exercitibus. Eos ipsos quos cernant legatos non pinnis sublime elatos Alpes transgressos. Ne maiores quidem eorum indigenas sed advenas Italiae cultores has ipsas Alpes ingentibus saepe agminibus cum liberis ac coniugibus migrantium modo tuto transmisisse. Militi quidem armato nihil secum praeter instrumenta belli portanti quid invium aut inexsuperabile esse?
Eorum here seems to me to refer to the legatos which I guess sort of makes sense, but then he's saying that the Romans (the ancestors of these particular Roman delegates) aren't indigenous to Italy—or maybe to the Alpine region?—and in fact migrated there themselves a long time ago.
The translation I've been looking at online agrees with this, but my Bristol Classics edition has a footnote for "ne maiores quidem" that refers to something in Book V called the Gallic migration where it seems like he is writing of Gaulish tribes migrating into Italy that displaced Etruscans et al.
This is news to me (didn't the Latins or Italic tribes displace those other peoples?) but is the idea that Gauls are the ancestors of Italians? If Livy means the Romans here, what's going on with this footnote?
