This is very true for me. Same for a lot of history museums, which are full of historic arts and crafts.

Like, some native art is just old craft, not actually good art to me, but some ancient cultures had a wild perspective and the art matches.

Lobotomy, electroshock and castration are historic treatments for various extreme mental disorders that were, probably mistakenly, considered necessary evils lacking other treatments.

These days prozac, benzos and lithium fall into a similar category.
