Bakst

If you like Barbier's illustrations and art, be sure to look at Léon Bakst's [1866–1924] work and Erte [1892-1990] for his art deco work as well. Léon Samoilovitch Bakst (Russian: Лео́н Никола́евич Бакст) was also a costume designer for the Ballets Russes, and has some great connections to dance and art. The image above his his idea for a costume for Helen of Sparta; more info and larger image here. Look here for more of his work; what an incredible style.

Similarly interesting is the supposedly Priam's treasure [ie. the king of Troy during The Iliad] that archaeologist Heinrich Schliemann discovered. Be sure to see the golden headdress, it's incredible! He even had his wife pose all dressed up in it and other jewels they found, but it's a black and white photo--the real gold looks amazing in color.
