Horace, Epistulae 1.1.53-56:
“Ō cī|vēs, cī|vēs, quǣ|rēndă pĕ|cūnĭă | prīmum ēst;
vīrtūs | pōst nūm|mōs!” Hǣc | Jānūs | sūmmŭs ăb | īmō
prōdŏcĕt, | hǣc rĕcĭ|nūnt jŭvĕ|nēs dīc|tātă sĕ|nēsquĕ.
“Hey, citizens! Citizens! Seeking money should come first – virtue after dollars!” This is what the Janus teaches from end to end; the young and the old repeat this lesson.
The Janus Medius was “the place in the forum where bankers and speculators gathered for business.”
