question:
Question: What present day country was Pontus? Passage:According to the Georgian chronicles, Nana was "from a Greek territory, from Pontus, the daughter of Oligotos" whom Mirian married after his first wife died (in 292 according to Cyril Toumanoff). Nana bore Mirian two sons: Rev II, Varaz-Bakur and a daughter who married Peroz, the first Mihranid dynast of Gugark. Pontus here may refer to the Bosporan Kingdom, then a client state of the Roman Empire. Toumanoff has assumed that the name of Nana's father might have been a Georgian corruption of "Olympius" or "Olympus", a Bosporan dynast whose son Aurelius Valerius Sogus Olympianus, a Roman governor of Theodosia, is known from a Greek inscription of 306 dedicated to "the Most High God" on the occasion of the building of the Jewish "prayer house". Alternatively, Christian Settipani identifies Nana as a younger daughter of Theothorses, a Bosporan king.

question:
Question: Who was the most famous artist associated with the art of Japan Bing publicized in Europe? Passage:The Franco-German art dealer and publisher Siegfried Bing played a key role in publicizing the style. In 1891, he founded a magazine devoted to the art of Japan, which helped publicize Japonism in Europe. In 1892, he organized an exhibit of seven artists, among them Pierre Bonnard, Felix Vallotton, Edouard Vuillard, Toulouse-Lautrec and Eugene Grasset, which included both modern painting and decorative work. This exhibition was shown at the Societe nationale des beaux-arts in 1895. In the same year, Bing opened a new gallery at 22 rue de Provence in Paris, the Maison de l'Art Nouveau, devoted to new works in both the fine and decorative arts. The interior and furniture of the gallery were designed by the Belgian architect Henry Van de Velde, one of the pioneers of Art Nouveau architecture. The Maison de l'Art Nouveau showed paintings by Georges Seurat, Paul Signac and Toulouse-Lautrec, glass from Louis Comfort Tiffany and Emile Galle, jewellery by Rene Lalique, and posters by Aubrey Beardsley. The works shown there were not at all uniform in style. Bing wrote in 1902, "Art Nouveau, at the time of its creation, did not aspire in any way to have the honor of becoming a generic term. It was simply the name of a house opened as a rallying point for all the young and ardent artists impatient to show the modernity of their tendencies."
