That river in Egypt

"This is Jupiter And Semele, painted by Gustave Moreau between 1894 and 1895. Like his other painting that I saved, I like the amount of detail that has gone into all the textures. You can get a sense that there's a lot there, but you can only really see it when zooming in. It must have been a massive pain to paint"
