Beauty is not a quality of the objects, since ever beauty has been corresponding with the aesthetic values of time. An historian of art like me must tell art as it really is and that has not to be the expression of my own opinion. Beauty in art is not merely "it is beautiful to me", but something more general and complex involving different aspects of the culture. Fortunately human body has not much changed over time, beauty arising in the time has remained broadly the same: harmony, balance, vitality have not changed.
