Paintings to see before you die

Here is a Guardian list, via CrookedTimber.  It is not bad, but surely Giotto’s Padua murals (this panel is clearer) should be added, Rembrandt’s Anatomy Lesson of Dr. Tuyp is far better than his Aristotle Contemplating the Bust of Homer, and how about Thomas Eakins’s The Gross Clinic?  I am not anti-Picasso but Guernica is in my view overrated.  How about this one?  El Greco’s Toledo picture is another contender. 

Try this list too.  Your thoughts?
