One can love the old masters (and mistresses, btw, as women have often made art but its been ignored quite deliberately by male art historians until relatively recently)

- I've posted a picture by Artemisia Gentileschi (1593 -1656) who was a celebrated Italian Baroque painter, recognised today as one of the most accomplished artists of her generation, but by no means not the only one: many daughters worked in there fathers studios and their work was attributed to father/husband. One pic is her as artist, but interestingly, she portrays in the other Susanna, in the bible, where the traditional interpretation was that she somehow "lured" men, but here is seen as victim.

One can love the paintings of yesteryear, becuase the ones that survive in our hearts and memories or in art history books are maybe the best of their time, whereas in our time, we cannot know what will survive into the future as the Zeitgeist of the time.
I have no doubt that Banksy will survive, but probably only the most liked and appreciated, but he'll be classed amongst others who made subversive or sometimes transgressive art, but them this is one of the functions of art in our time.
In the past, most artists only made a living, unless they had private means, by either having a patron whom they had to please, or at least sell art work on the basic of what the rich or perceptive middle classes could afford, or they "starved in a garret" and there work after death gradually started becoming valuable as their particular genre became accessible.
Remember even the impressionists were once very ill thought of at their time - What shocking loose brush work! What vague outlines! How dare they portray everyday themes, not religious or Important Person representations!
Even Turner, whom I imagine we all love, was not at all popular. How vague! The exaggerated colour!
