Santorini, officially Thira, is an island located in the southern Aegean Sea, about 200 km (120 mi) southeast from Greece's mainland.
Santorini is essentially what remains after an enormous volcanic explosion that destroyed the earliest settlements on what was formerly a single island, and created the current geological caldera. A giant central lagoon, more or less rectangular, and measuring about 12 by 7 km (7.5 by 4.3 mi). The main island slopes downward from the cliffs to the surrounding Aegean Sea.
It is the most active volcanic centre in the South Aegean Volcanic Arc, though what remains today is chiefly a water-filled caldera. The region first became volcanically active around 3–4 million years ago, though volcanism on Thera began around 2 million years ago with the extrusion of dacitic lavas from vents around the region of Akrotiri.
The island is the site of one of the largest volcanic eruptions in recorded history: the Minoan eruption (sometimes called the Thera eruption), which occurred some 3600 years ago at the height of the Minoan civilization. The eruption left a large caldera surrounded by volcanic ash deposits hundreds of feet deep and may have led indirectly to the collapse of the Minoan civilization on the island of Crete, 110 km (68 mi) to the south, through a gigantic tsunami. This theory is not, however, supported by chronology, in that the collapse of the Minoan civilization did not occur at the date of the tsunami, but some 90 years later. Another popular theory holds that the Thera eruption is the source of the legend of Atlantis.
Ravensburger HistoryRavensburger Spieleverlag GmbH is a German game company and market leader in the European jigsaw puzzle market.
The company was founded by Otto Robert Maier with seat in Ravensburg, a town in Upper Swabia in southern Germany. He began publishing in 1883 with his first author contract. He started publishing instruction folders for craftsmen and architects, which soon acquired him a solid financial basis. His first board game appeared in 1884, named "Journey around the world".
At the turn of the 20th century, his product line broadened to include picture books, books, children’s activity books, Art Instruction manuals, non-fiction books, and reference books as well as children’s games, Happy Families and activity kits. In 1900, the Ravensburger blue triangle trademark was registered with the Imperial Patent office. As of 1912, many board and activity games had an export version that was distributed to Western Europe, the countries of the Danube Monarchy as well as Russia.
Before the First World War, Ravensburger had around 800 products. The publishing house was damaged during the Second World War and continued to produce games in the years of the reconstruction. The company focused on children's games and books and specialized books for art, architecture and hobbies, and from 1962 grew strongly. The company started to produce jigsaw puzzle games in 1964, and in the same year opened subsidiaries in Austria, France, Italy, the Netherlands, Switzerland and the United Kingdom. In 1977 the company split into a book publishing arm and a game publishing arm.
Today there are approximately 1,800 available books and 850 games as well as puzzles, hobby products and CD-ROM titles at Ravensburger and its subsidiaries, which include Alea for "hobby and ardent game players" and FX Schmid for games and children's books. Ravensburger products are exported to more than fifty countries.
In September 2010, Ravensburger broke Educa's record for the world's largest jigsaw puzzle of 24,000 pieces. Ravensburger's new puzzle design by late pop artist Keith Haring titled, 'Keith Haring: Double Retrospect' breaks the Guinness Book of World Records measuring 17' × 6' built from 32,256 pieces and comes with its own dolly cart for toting.
