A Pastoral Capriccio: Evening

This is "A Pastoral Capriccio with the Arch of Kostantine and the Colloseum: Evening" 1651, Claude Gellée le Lorrain.

I got it , amongst other gems in a book on the Treasure Houses of Britain
(which might just prove to be a treasure trove for this blog, since there's just so much in there)

A grand orange garden, 

a city with an interesting Mountain Grotto and what looks like a slightly military scene

an Ominous looking evening shore, where you can almost hear Liz Fraser singing a song to the Siren

when you know it will end in tears
