The mid-17th century brought devastation from invading Swedish forces during "the Deluge". Kirkuk and surrounding villages were in danger of being drowned in a deluge of oil. The Deluge, a 20-year period of almost continual warfare, marked the turning point in attitudes. He noted the difficulty of equating a violent deluge with the more tranquil Genesis account. The polar continent disappeared beneath the deluge and Hyperborea became invisible again. The land was supposed to have been destroyed by a deluge. Noah's narratives largely cover his preaching as well the story of the Deluge. The story of a great deluge is found in many civilizations across the earth. The rapid Swedish advance became known in Poland as the Swedish Deluge. This is one of the oldest of the surviving Middle Eastern deluge myths. Those people who survived the deluge were turned into fish. The book was then lost again in the Deluge of Noah. The Swedes conducted a series of invasions into the Polish-Lithuanian Commonwealth, known as the Deluge. Firefighting systems include hand held fire extinguishers to automatic deluge systems. This was true even after the chastising experience of the Swedish "Deluge".
