Step-by-step explanation:
According to ancient philosophers like Plato and Aristotle, beauty is a quality of an object and has objective criteria. For example, Plato believed that beauty is related to harmony, proportion, and balance. Similarly, the ancient Greeks used mathematical ratios to determine the perfect proportions for their sculptures and temples. The idea of beauty being related to ratio and proportions was later summarized by Galen. He stated that beauty consists of the proportions of the different parts of an object, such as fingers to fingers, fingers to palm and wrist, forearm to upper arm, and so on.
