Question: How long had the Rodin Museum been around for by the year Auguste Rodin created a bust of Lord Howard de Walden? Passage:After succeeding to his family titles in 1899 he inherited further estates in 1901, including property in Marylebone, London and earned the title of 'Britain's wealthiest bachelor'. His family's wealth was initially derived from slavery and sugar estates in Jamaica, primarily Montpelier, Jamaica. He took a lease on Audley End House, Essex which had once belonged to his ancestors, in 1904 but reportedly never felt settled there. The artist Auguste Rodin created a bust of Lord Howard de Walden in 1906 which is held in the collection kept at the Rodin Museum in Philadelphia. In 1911, in preparation for his marriage, he leased Chirk Castle, Denbighshire, which became his main residence after WWI until 1946, and where he learned the Welsh language; he later served as president of the Campaign for the Protection of Rural Wales from 1931 to 1945.

Question: How many soldiers fought under the combined Cossack-Tatar side under chief Asand Demko? Passage:He began his studies in Poland and continued his education at the University of Leuven. His considerable wealth enabled him to establish his own private army, which suppressed Cossack riots and Tatar raids in Ukraine. In 1635 he became the first voivode of the Czernihów Voivodship. In 1646 he was appointed Field Crown Hetman. During the Khmelnytsky Uprising, he was captured by the Tatars after the Battle of Korsun in 1648. He was a prisoner-of-war until 1650 when he was ransomed. On 12 May 1651 he commanded victorious Polish army in the Battle of Kopyczyńce between Poles and combined Cossack-Tatar forces under chief Asand Demko. In 1651, during the subsequent hostilities between the Commonwealth and Cossack-Tatar alliance, he was the nominal commander of the Polish army right wing at the great victorious Battle of Beresteczko (de facto commanded Jeremi Wiśniowiecki). Upon death of Grand Crown Hetman Mikołaj Potocki, who was his political and personal adversary, hetman Kalinowski commanded the choicest elements of the Commonwealth army and he had at the camp at Batoh about 10–12,000 soldiers and 10–15,000 servants and camp followers. This army was surprised by the combined Cossack-Tatar army, consequently defeated and then capture of Polish soldiers and servants resulted in a wholesale slaughter of the best elements of Commonwealth army and their retinues, the event known as Battle of Batoh. Hetman was killed on 2 June 1652, during the last day of the battle, when trying to escape from the Cossack-Tatars-filled burning Polish camp, in woods some 3 kilometers from the Polish camp. Hetman's severed head was carried around the Cossack-Tatar camps, allegedly by the Nuredin-Sultan himself.

Question: What are the English equivalent words for Arzawa and Kizzuwatna? Passage:To the west and south of the core territory lay the region known as Luwiya in the earliest Hittite texts. This terminology was replaced by the names Arzawa and Kizzuwatna with the rise of those kingdoms. Nevertheless, the Hittites continued to refer to the language that originated in these areas as Luwian. Prior to the rise of Kizzuwatna, the heart of that territory in Cilicia was first referred to by the Hittites as Adaniya. Upon its revolt from the Hittites during the reign of Ammuna, it assumed the name of Kizzuwatna and successfully expanded northward to encompass the lower Anti-Taurus Mountains as well. To the north, lived the mountainous people called the Kaskians. To the southeast of the Hittites lay the Hurrian empire of Mitanni. At its peak, during the reign of Muršili II, the Hittite empire stretched from Arzawa in the west to Mitanni in the east, many of the Kaskian territories to the north including Hayasa-Azzi in the far north-east, and on south into Canaan approximately as far as the southern border of Lebanon, incorporating all of these territories within its domain.
