Julius Caesar: Lupercalia Connection

Plutarch

ἐπιγίνεται τούτοις τοῖς προσκρούσμασιν ὁ τῶν δημάρχων προπηλακισμός. ἦν μὲν γὰρ ἡ τῶν Λουπερκαλίων ἑορτή, περὶ ἧς πολλοὶ γράφουσιν ὡς ποιμένων τὸ παλαιὸν εἴη, καί τι καί προσήκει τοῖς Ἀρκαδικοῖς Λυκαίοις.
τῶν δ᾽ εὐγενῶν νεανίσκων καί ἀρχόντων πολλοὶ διαθέουσιν ἀνὰ τὴν πόλιν γυμνοί, σκύτεσι λασίοις τοὺς ἐμποδὼν ἐπὶ παιδιᾷ καί γέλωτι παίοντες πολλαὶ δὲ καί τῶν ἐν τέλει γυναικῶν ἐπίτηδες ὑπαντῶσαι παρέχουσιν ὥσπερ ἐν διδασκάλου τὼ χεῖρε ταῖς πληγαῖς, πεπεισμέναι πρὸς εὐτοκίαν κυούσαις, ἀγόνοις δὲ πρὸς κύησιν ἀγαθὸν εἶναι.
There was added to these causes of offence his insult to the tribunes. It was, namely, the festival of the Lupercalia, of which many write that it was anciently celebrated by shepherds, and has also some connection with the Arcadian Lycaea.
At this time many of the noble youths and of the magistrates run up and down through the city naked, for sport and laughter striking those they meet with shaggy thongs. And many women of rank also purposely get in their way, and like children at school present their hands to be struck, believing that the pregnant will thus be helped to an easy delivery, and the barren to pregnancy.
