On the subject of delusions of grandeur. If you're thinking about seeing the Bosch and Bruegel: Inventions, Enigmas and Variations you might like to consider that it's in Room 1 and contains about 10 paintings/drawings. If you thought, because of the exhibition title, that it was about Bosch, note also that just one of the paintings is by Bosch. At least it's free, bar a donation and worth a look if you're in the area.
