Beauchamp, superintendent of the ballet and director of the Académie Royale de Danse codified the five positions based on the foundations set down by Thoinot Arbeau in his 1588 Orchesographie. Emphasising the technical aspects of dance Beauchamp set out the first rules of ballet technique. Pierre Rameau expanded on Beauchamp's work in Dancing Master 1725 further detailing carriage of the body, steps and positions. Jean-Philippe Rameau's Les Indes Galantes (1735) is considered to be the work that signaled the divergence of social (ballroom) dance and ballet. The emphasis on turned out legs, light costumes, female dancers and long dance sequences (all first seen in L'Europe Galante (1697)) with light, flexible footwear was a turning point in ballet practice that lead to Pre romantic ballet era.
