Macrobius, Saturnalia (II.2.3.1-4)
“I am surprised that you all have been quiet about Cicero’s jokes which prove him as eloquent as in everything else he said. If it seems right, I am prepared—like the guardian of a temple about to announce the oracles of a god—to repeat the Ciceronian jests I remember.
When everyone appeared ready to listen to him, he began: “When Marcus Cicero dined with Damasippus and his host offered him a rather middling wine and said “Drink this forty-year old Falernian,” Cicero replied “It carries its age well.” At another time when he saw his own son-in-law Lentulus, a man of short stature, girded up with a long sword, he asked “Who has attached my son-in-law to a sword?” Nor did he keep a similar bite from his brother Quintus Cicero. For, when visiting the province Quintus that was administering, he saw his brother’s portrait armed with a circular shield sculpted with much greater size near the chest in the manner of pictures (his brother was also a bit on the shorter side), he said “Half of my brother is bigger than the whole!”
Sed miror omnes vos ioca tacuisse Ciceronis, in quibus facundissimus, ut in omnibus, fuit: et, si videtur, ut aedituus responsa numinis sui praedicat ita ego quae memoria suggesserit refero dicta Ciceronis. Tum omnibus ad audiendum erectis ille sic incipit: 2 M. Cicero, cum apud Damasippum coenaret et ille mediocri vino posito diceret: Bibite Falernum hoc, annorum quadraginta est: Bene, inquit, aetatem fert. 3 Idem cum Lentulum generum suum, exiguae naturae hominem, longo gladio adcinctum vidisset: Quis, inquit, generum meum ad gladium alligavit? 4 Nec Q. Ciceroni fratri circa similem mordacitatem pepercit. Nam cum in ea provincia quam ille rexerat vidisset clypeatam imaginem eius ingentibus lineamentis usque ad pectus ex more pictam (erat autem Quintus ipse staturae parvae), ait: Frater meus dimidius maior est quam totus.
