I just discovered this lovely community yesterday, and I thought I'd introduce myself. My favourite movement in art is Symbolism, and I recently started a blog on the Decadent movement which has regular discussions of Symbolists, and the more bizarre and disturbing aspects of 19th century art. I've posted a few paintings by some of my favourite artists below the cut.
'Dante Drinking From the Waters of the Lethe' - Jean Delville
'The Sacred Wood' - Arnold Bocklin
'Unicorns' - Gustav Moreau
'White Peacocks- - William Degouve de Nuncques
'Field of the Slain' - Evelyn de Morgan
'Love' - Gustav Klimt
'Spleen and the Ideal' - Carlos Schwabe
Loads more can be found on my Flickr art stream. Hope to post more soon!
