I'm copy pasting this from SSC - my views on the new AGO.
I spent 3h in the AGO today.. Here's my critique (and direct comparison to the National Gallery in Ottawa).
From first glance, you'd expect them to arrange the European galleries in a chronological order, or at least by style. The AGO having relied so heavily on private donations has split the European galleries by donators which has left a piece meal impression on me (I couldn't completely consolidate everything). The NGC has galleries by styles which makes it much easier to appreciate when its contemporaries hang alongside them.
The collection: well impressive. The NGC, I felt, had a far larger amount of sculptures and especially medieval European religious art, but the ones displayed in the AGO were far more impressive. The first gallery you're most likely to walk into is the Italian renaissance gallery. First Bernini's 'Corpus' stands in the middle of the room, far smaller than I expected, but still humbling. Alongside the walls there are two Tintorettos I believe, a Carvagghio, and for some reason a French renaissance painter whose name escapes me atm. Going along the left side to the next galleries you are greeted by more Italian art, a room of Dutch portrait painters from the 17th century with some great examples of the incredible realism of Hals' paintings. Eventually you reach the Thomson galleries.
Thomson donated an incredible amount of art and such an amusing amount of little trinkets! There were these interesting beer mugs made of carved ivory depicting mythological scenes of rape, murder, love.. Whatever you could possibly muster! Eventually dragging your feet through all these trinket galleries you reach one room dedicated solely to Rubens. In the back stands the Massacre of the Innocents, absolutely breathtaking from the scene it depicts to the execution. The detail is just so astounding that you can't help but stand and stare. To my surprise on the left stood an even bigger Rubens: Samson and Delilah. Reading about it I see this seems to be a loan from the National Gallery in London, probably reciprocity over having Massacres hanging there for a few years. There are a few anatomical sketches by Rubens on the far wall.
One room particularly amazed me; The Parisian salon. An entire wall is plastered with dozens of fairly large paintings from French impressionists to the English (Turner, Reynolds, etc) and with a few Canadian artists in there as well. Rodin's the thinker and Adam stand in the middle. One particular painting particularly caught my fancy. I believe it is an English artist of an Italian noblewoman with red hair and a naughty expression about her. She seems as if she's taunting you with a little secret she knows.
There are a few random galleries throughout the European section with strewn works by Poussin, Renoir, Magritte, Picasso - without any sort of order which bothered me greatly.
The Canadian collection is far, far greater than the collection at the National Gallery. It is well known that the AGO is the place to go to if you have a fetish for copious amounts of group of seven works.
The modernism tower was... Interesting. I'll admit, modernism is not my cup of tea, but I did enjoy the Warhol and reading those funny interactive pieces of art with random sentences strewn together.
Overall, while the National Gallery has a richer collection of European art, the AGO delivers more 'blockbusters'. Now whether this is a good thing, or a bad thing is up to you. I enjoyed it, but left slightly unimpressed.
I saw one of the UT members there... Saw his pic somewhere on the forum, but recognized him instantly at the gallery.
