I saw a documentary about Pompeii, the remains of which really are about 1/4 brothels. The best scholarship today suggests that far from being an unusual "LasVegas-like" sexpot, Pompeii was TYPICAL of the Roman Empire, just frozen in time in AD 68.
Therefore in an environment not unlike Sodom, Christianity was born and the ethics of the New Testament flourished...which of course included sexual purity and rescuing babies from infanticide.
That’s why it was “good news” to them, when they heard the Gospel. It was a big relief.
From what I have seen on tv, time with a prostitute in Roman Times cost the same as a loaf of bread.
I was most fortunate to be able to visit Pompeii on several occasions. It is such a fascinating place. In one of the private homes, there is a fresco with a small, locked box obscuring a portion of it. For a few extra lire, the tour guide will unlock the box to reveal the .. ahem .. rest of the fresco.
