John Briscoe (ed.), A Commentary on Livy Books XXXI–XXXIII
3. in monte Albano … dixit: L. himself gives only two other cases of triumphs on the Alban mount, Marcellus in 211 (xxvi. 21. 6) and C. Cicereius in 172 (xlii. 21.7). The first Alban triumph was by C. Papirius Maso in 231 (Fasti Triumph., Piso, HRR i2. 135, fr. 31, Val. Max. iii. 6. 5). As iure imperii consularis indicates, it would appear that the senate could not refuse a triumph tout court but only pg 293the funds for the expenses (cf. § 8 below). The Alban Mount (Monte Cavo) was a considerable distance from Rome, and the climb to the summit far from easy, so the number of spectators is unlikely to have been all that large.

6. pilleatorum: the pilleus was a soft cap worn by freed slaves at their manumission. The people of Placentia and Cremona were thus indicating that their release from Gallic captivity was tantamount to being freed from slavery. Cf. the similar action by Q. Terentius Culleo at the triumph of Scipio Africanus (xxx. 45. 5). See addenda.
7. duplex equiti centurionique: thus B. Mog. has duplex equiti, triplex centurioni. The latter is impossible—a centurion would not be given more booty than an eques. Hence Duker read duplex centurioni, triplex equiti. Ogilvie, Phoenix, 344, argues in favour of this on the grounds that other passages show the equites getting three times as much as the infantry (37. 12, xxxiv. 46. 3, 52. 11). But the amounts were a matter for the discretion of the commander, and it is not necessary for all divisions to have been the same. Duker's transposition, moreover, makes it difficult to explain B's text. (Brunt, 394, is unaware of B's reading and hence sees 37. 12 as a unique, and hence dubious, example of centurions and equites getting equal amounts.)
