Who is the most attractive person of all time?
Helen of Troy was not a documented person, but in the Iliad she is described as having "the face that launched a thousand ships"; that her beauty was so noteworthy she was worth starting a war for. I think it's important to note how significant that phrasing was, specifically with the focus being on her face. It implies a very significant value on that part of the aesthetic to the Greeks in the mid 700s BC.
If we skip ahead a few centuries to Cleopatra, the word that most gets used to describe her attractiveness is that she was "captivating". That people would be so drawn in talking with her that they couldn't let themselves leave. She's alleged to have been able to speak nine languages and that her ability to hold a conversation was legendary. That all said, we normally associate beauty with Cleopatra but I think her being significantly more educated than near anyone else in the area made her more noteworthy than just her appearance. I think Julius Caesar was just so overtaken by the idea that not only could there be people who were more knowledgeable than him, but her being a woman and royalty was one of the first ever instances of status maxxing influencing attraction on the world stage.
As we look to the Renaissance, a word literally meaning "rebirth". the focus is on returning to perspectives and ideals held by the Greeks and Romans of the classical era. Below I'll add the link to the Wikipedia for the painting of The Birth of Venus. I didn't post it here because I'm not sure how admin feels about artful nudity directly on the site. Venus (Aphrodite) is literally the goddess of desire. If we look at her features present in this painting, we see features of her face and body that I would assume to be traits considered the most attractive of the culture.
While I understand looksmaxing relies on concepts of universal attraction, I do think that there is room for cultural influence on these topics. One of the things I personally find very interesting is imagery of Joan of Arc. While photography wasn't a thing in the 1400s France, when looking at art made of her, there are some interesting consistent themes. Notably, she is quite attractive but exclusively in the lens of the female gaze. Her body is almost always covered by armor (a thing historically associated with masculinity), but her face is very consistently attractive despite wildly different designs. I bring her up because Joan of Arc has an undeniable place in queer, and specifically lesbian, circles. There is an argument to be made that she became the first ever femme paragon of queer individuals regardless of her personal sexuality.
