“Beauty has no obvious use,” writes Sigmund Freud, “nor is there any clear cultural necessity for it. Yet civilization could not do without it.” To celebrate its 150th anniversary, the National Archaeological Museum addresses a subject that for thousands of years has been central to human life: the beautiful. Different sections explore fundamental questions. What was the aesthetic in antiquity? How have standards of beauty changed? And most importantly, what is it about beauty that so enthralls us? This comprehensive show moves from Ancient Greek myths, to Neolithic relics, to more recent historic times. —E.C.
