El Greco: The Modena Triptych.
If you look closely, this exceptionally small work by El Greco seems to have inspired Spanish artists - and others - who came after El Greco. One such painter who comes to mind is Dali. We know El Greco began as an iconographer, but I wonder if he was influenced at all by Bosh?
Thanks to the ever popular Kat for introducing me to this El Greco. She offers the full frontal view here.
