Petronius's "insula" lay on the southern slope of the Palatine, near the so-called Carinæ; their nearest way, therefore, was below the Forum; but since Petronius wished to step in on the way to see the jeweller Idomeneus, he gave the direction to carry them along the Vicus Apollinis and the Forum in the direction of the Vicus Sceleratus, on the corner of which were many tabernæ of every kind.
Petronius insulája a Palatinus déli lejtőjén, az úgynevezett Carinae közelében épült, útjuk tehát a Forum felé vezetett volna, de mivel Petronius egyúttal Idomeneus ötvöshöz is be akart nézni, úgy intézkedett, hogy a Vicus Apollinison és a Forumon át vigyék őket a Vicus Sceleratus felé, amelynek sarka tele volt tabernákkal.
