Ancient Greek notions of beauty were based on the combination of mathematical proportions and the physiques of male athletes, as demonstrated by sculptors like Polykleitos and the cultural emphasis on athleticism.

Explanation:

The ancient Greek notions of beauty were based upon mathematical proportions and the finely honed physiques of male athletes. This is evident in the work of the Greek sculptor Polykleitos in the 5th century BCE who developed a canon – a set of mathematical rules for sculpting the human form to achieve an aesthetically pleasing and lifelike proportion. This notion of beauty was not solely for art's sake but also had a pragmatic aspect in that it reflected the Greek admiration for physical fitness and athletic competition, which was integral to their culture and preparation for war.

Therefore, the answer to what the ancient Greek notions of beauty were based upon is: 1) The combination of mathematical proportions and the physiques of male athletes.
