This is the “résumé” of the 15th century French poet Francois Villon:
People have wondered for a long time on what is beautiful and what isn’t. The Greeks certainly did, and even though they had set rules to define what the “right” proportions were for sculptures, buildings etc. they still had philosophers ready to challenge those ideals. Not sure if it was because they were dating someone ugly, but some of them decided that a bit of ugliness makes things prettier.
