Look closely, and you’ll see that there are phalluses everywhere within the city: hiding on the roads, adorning the walls, and even hanging above doorways and bread ovens.

Tour guides often tell visitors that the stone penises of Pompeii are one of the earliest known forms of advertising. According to these stories, the phalluses serve as arrows, and if you follow the arrows, you’ll wind up at one of the city’s many brothels.
