Anyway, down to business:
Franz Von Stuck is said to have been one of Hilter's favourite artists. Von Stuck's art is quite doom-and-gloomy and a lot of his paintings strongly feature religious and mythological figures but its the aesthetics of his paintings that I love most.

(Do you classicists recognize what the lower panel represents?)
Kiss of the Sphinx
Last but certainly not least is my very favourite Von Stuck painting:
Hope you liked!
