On that note I'm not sure what ancient religion has to do with the way sex work is viewed in the modern day United Kingdom.
Probably nothing directly. But it maybe casts an interesting light on the suggestion another poster made about religion being a main reason for the taboo, and how that relates to Christianity & current UK values.
Like Colston says, prostitution was in several cases sanctified by ancient Greek religion. While there was still some stigma towards WGs in ancient Greece, it was mostly quite mild, and there were many cases of WGs having influence as independent and wealthy citizens. Huh, several of the most elite type of ancient Greek WGs (hectaria) ended up marrying some of the most powerful Greek leaders. So religion in & of itself doesnt have to be anti WG.
There used to be a saying in ancient Greek that there were loads of statues build to honour the beautiful hectaria's , but very few to honour regular wives.
Strong stigma towards prostitutes the West only began in Roman times - and this was well before the Romans became Christian. Christianity was arguably on balance an influence back towards tolerance of prostitution. Many elements of Christiantity were pro women & even pro WG. There's Christ's example of preventing the stoning of the fallen woman. The fact the "Disciple he loved best' (Mary Magdalene) was long regarded as a WG (though that's not the mainstream view these last 40 years or so) . Before Christianity took over as the official religion of the Roman empire, it was described by historians as the religion of slaves & women. Right from the early days, some of the most influential Church fathers like Augustine spoke out in favour of allowing brothels in Christian cities - which is part of why they've often been tolerated down the ages. Much pro sex work advocacy is still done by Christians today.
Which is not to deny many Christians have & continue to be extremely oppressive towards women & WGs. But it's a mixed picture. Apart from what was said about religion, I agree with the points made by Tender.French.Kiss.
PS not going to say anything more about religion as I think the mods dont like too much focus on that, even when it's directly linked to punting. But just in case anyone wanted to verify about WGs being largely celebrated in ancient Greek , but then stigmatised in ancient Rome & the rest of western history, a good book to read is 'Prostitutes and Matrons in the Roman world', esp. the first chapter.
