This is what they say about themselves:
Artsy’s mission is to make all the world’s art accessible to anyone with an Internet connection. We are a resource for art collecting and education.
"Monet's bio, over 75 of his works, exclusive articles, as well as up-to-date Monet exhibition listings. The page even includes related artist and category tags, plus suggested contemporary artists, allowing viewers to continue exploring art beyond our Monet page."
The site features a lot of artists, from Rembrandt to contemporary artists. You can find painters, sculptors, photographers and designers. It's indeed a great resource and certainly fun to browse through all this wonderful art and discover new artists.
