comites: the technical word for members of the cohors of a provincial governor; cf. Catul. 28.1; Catul. 46.9; as Catullus may now hope to be a comes of Caesar, Furius and Aurelius have offered to be his humble and useful friends, that they may profit by his good fortune, and Catullus ironically terms them his comites.
 extremos Indos: cf. Hor. Ep. 1.1.45 “impiger extremos curris mercator ad Indos” ; Prop. 2.9.29 “quid si longinquos retinerer miles ad Indos” ; Stat. Silv. 3.2.91 “vel ad ignotos ibam comes impiger Indos.”
 Eoa unda: i.e. the all-encircling ocean-stream at the extreme East; cf. Ov. Fast. 6.474 “vigil Eois lucifer exit aquis” ; Tib. 4.2.20 “proximus Eois Indus aquis” ; Verg. G. 2.122 “quos Oceano propior gerit India lucos.”
 Hyrcanos: a people dwelling by the southern end of the Caspian Sea (Mare Hyrcanum), joined by Vergil with the Arabians and Indians as distant enemies of Rome; cf. Verg. A. 7.605 “[sive bellum] Hircanis Arabisve parant seu tendere ad Indos.”
 sagittiferos Parthos: with reference, as very often in Latin literature, to the traditional weapon and manner of fighting of these most dreaded enemies of Rome; cf. Hor. Carm. 2.13.17 “miles [timet] sagittas et celerem fugam Parthi” ; Ov. Rem. Am. 157 “vince Cupidineas pariter Parthasque sagittas” ; Stat. Theb. 6.575 “[credas] Parthorum fuga totidem exsilvisse sagittas.”
 In this and the two following verses is a trace of the reconciliation of Catullus to Caesar; cf. Intr. 38ff. The poet could not yet sing Caesar's praises unreservedly, though he might have done so had he lived longer; but he has already yielded from his earlier position ofunmixed censure.
 monimenta: the places mentioned are themselves the reminders of Caesar's greatness.
 ultimos: cf. Catul. 29.4 Catul. 29.12; Hor. Carm. 1.35.29 “serves iturum Caesarem in ultimos orbis Britannos” ; Verg. Ecl. 1.66 “penitus toto divisos orbe Britannos.” The preliminary invasion of Britain took place in the late summer of 55 B.C.
[13-16] Apparently Furius and Aurelius, at the suggestion of Lesbia, tendered their services in bringing about a reconciliation with her; but Catullus thoroughly despises them for their actions in the past (cf. Intr. 37), and employs them as comites on only one, and that a final, errand, - to convey to Lesbia his decision against her appeal.
 meae puellae: in half-scornful, half-mournful reminiscence of such passages as Catul. 2.1 and Catul. 3.3; cf. the tone of Catul. 58.1 Possibly Lesbia in this appeal had called herself by the endearing name that her lover used to apply to her.
 trecentos: colloquially used of indefinite multitude; cf. Catul. 9.2n.; Pl. Mil. Glor. 250 “trecentae possunt causae colligi” (but Pl. Trin. 791 “sescentae causae possunt colligi” ); Hor. S. 1.5.12 “trecentos inseris!” and often elsewhere.
 velut: love then languished only, but is now dead and cannot be recalled to life; with the figure, cf. Verg. A. 9.433 “purpureus veluti cum flos succisus aratro languescit moriens” , though Catullus secures greater delicacy of expression by introducing ultimi prati, and by using tactus instead of succisus.
