Question: Who governed Noricum after the Romans turned it into a province? Passage:Archaeological findings in the area date back to the Neolithic era, especially the stilt houses of the Mondsee group culture, who settled the region from about 3800 BC onwards. The Germanic name hall of several settlements refers to the region's numerous salt mines, which had been in use at least since the days of the Celtic Hallstatt culture, centered at the mining town of Hallstatt. These operations were continued by the Romans, after the area had been incorporated into the Noricum province in 15 BC. A Roman settlement and salt evaporation pond at Hallstatt is documented about 100, affected by several Germanic invasions after the Marcomannic Wars, until the province was finally evacuated at the behest of the Italian king Odoacer in 488.

Question: How old was the explorer, pastoralist and historian  who was part of the exploration of Wide Bay district when he died? Passage:The free settlement of what later became the colony of Queensland commenced on the Darling Downs in 1840. In 1842, the same year that Moreton Bay was opened to free settlement, Andrew Petrie was commissioned to explore the Wide Bay district. With a group of men that included Henry Stuart Russell, the explorer, pastoralist and historian, Petrie travelled by boat to explore the Mary River (then unnamed) as a possible source of Bunya trees. The explorers travelled about upstream, and it was concluded that the area would prove suitable for sheep rearing as the river would allow wool to be transported by boat. One of the men, Captain Joliffe, was an employee of the pastoralist and businessman John Eales, who later took up a large run at Tiaro and sent Joliffe there with 16,000 sheep. Although this venture failed, due to a combination of disease, attacks by the traditional owners, and financial problems, other pastoralists soon took up runs in the area. By 1847 more than 20 license applications for runs had been lodged in the region. In July 1847 the government surveyor James Charles Burnett gave encouraging reports of the suitability of what was then known as the Wide Bay River as a location for a port to service the area. The river was then named Mary after Lady Mary Lennox, the wife of Governor Fitzroy.
