Every history has a starting point and most roller coaster historians agree that the ride's origins were the Russian Ice Slides（滑翔）. These slides first appeared during the 17th century throughout Russia. The structures were built out of lumber（木材）with a sheet of ice several inches thick covering the surface. Riders climbed the stairs tied to the back of the slide, sped down the 50 degree drop and go up the stairs of the slide that laid parallel（平行的）to the first one. It is said that Catherine the Great was a large fan of the slides and had a few built on her own property.

　　There is some disagreement as to who actually added wheels and created a rolling coaster. Robert Cartmell, who wrote the book A History of the Roller Coaster, gives the Russians belief for building the first wheeled machine… Other historians say it was the French who added wheels to the slides. It is known that by 1817 two coasters were built in France.

　　The Aerial Walk, one of the two coasters featured a heart-shaped design with two tracks that flowed in opposite directions from a central tower. They then went around the course, came together at the bottom and go up parallel. The first looping（多圈的）coaster was in Frascati Gardens in Paris, France. The hill was 43 feet high, had a 13 foot-wide loop and tested with everything under the sun before humans were allowed on. The design was simple：the rider rode down the gentle slope（斜坡）on a small cart and through a metal circle.

　　The ride ran for about twenty seasons and the pleasure railway grew old-fashioned. A Centrifugal Railway was built in the Circus Napoleon, but failed in an accident on the trial run and was quickly shut down. It was several years before a man named La Marcus Thompson created the first roller coaster in the United States and change the amusement industry forever.
