Fact is, it's improved. The reason is irrelevant. A 1700's man would think a 2014 woman looked and smelled like an angel.
Social conventions of the time equated a little chubbiness with wealth. However, outright obesity was still considered unattractive, and athletic builds were held in even higher esteem.
Surely you're not serious, are you? Are James Cameron, Steven Spielberg, and Michael Bay drawing millions of people into art galleries for hundred-million-dollar opening weekends of their latest art exhibitions? Are there 57 channels on my TV devoted to the art world? (Is there even one?) There are multiple channels devoted to music and movies, but nothing on traditional painting. And you seriously wrote that it's the "top of the art world?" How many millions of people tuned in to watch the Grammies? The Oscars? The Emmys? Heck, even the Tony awards? Now how many people give 2 sh*ts about an art auction?
"Top of the art world." OK.
I didn't say there were no better options (for example, maybe wine was pretty good back then). I'm simply saying the very best beer from 800 AD would be vastly, vastly inferior in flavour to virtually any beer produced in 2014. But since drinking 2014 beer was not an option in 800 AD, and 800 AD beer was all they ever knew, they developed a palate for the flavour and maybe even thought it was pretty good. But that doesn't mean that - given the chance - they wouldn't have found today's beer far superior.
