Art

It has come to my attention that today is World Art Day – an occasion that seems to be little marked here: no going to school dressed as your favourite painting, or at least clutching a reproduction thereof (perhaps just as well – it would probably be wall-to-wall Van Goghs, with the odd Monet). Anyway, I thought I'd mark the day by naming what I believe to be the greatest paintings of, as they say, 'all time' – limiting the list to those I've actually seen with my own eyes. The list I came up with shows, if nothing else, that my (visual) aesthetic sense is rooted firmly in one quite narrow period of time (though there's one outlier, from the 15th century) – or does it show that that was when painting reached its peak? 
  So, in no particular order...

Any and all of Titian's four 'Poesie'
Rembrandt's Night Watch
Vermeer's View of Delft
Tintoretto's Crucifixion
Van Eyck's Ghent Altarpiece
Velazquez's Las Meninas
Titian's The Flaying of Marsyas
Bellini's San Zaccaria Altarpiece
Giorgione's Tempest
Rembrandt's Anatomy Lesson

Any thoughts?
