Yes, love Pepys musings. He writes plenty on beauty spots.

So Hogarth was satirizing the marriage market in this one. Thus, why most art historians believe those are syphilis marks.

Beauty spots were more typically used to cover smallpox scars but they just wouldn't get the job done as syphilis advanced. I could ask you to google advanced stages of syphilis but...you might be eating lunch and then I would seriously wreck your day. ;)
