Carlo Blasis

Work He published an analysis of the ballet techniques in 1820, in a work named Traité élémentaire, théorique, et pratique de l'art de la danse ("Elementary, Theoretical, and Practical Treatise on the Art of the Dance"). He is most known for the pose "Attitude" derived from the famous statue Mercury by Giovanni da Bologna. Enrico Cecchetti expanded his method of instruction and theories.

Even during his own time, Blasis was not best known for his many choreographies (none of which survive today), but for his writings on dance theory. He pioneered the reconciliation of balletic notions like lightness and grace with the geometry and physics of the body in motion. In The Code of Terpsichore, published in 1828, Blasis cataloged a clearly defined "alphabet" of dance poses. This may be the first attempt at a comprehensive systemization of dance.

Blasis radicalized dance theory by relying heavily upon mathematical geometry and physics. He introduced the idea of a "movement axis" – a vertical line through the pose, perpendicular to the floor, that delineates the center of balance of the body. Thus, Blasis ultimately wished for dancers to layer emotional expression on top of the codified, regimented poses demanded by the choreography and outlined in The Code of Terpsichore.

Through these practices, Blasis aimed to direct "the newborn Romantic ballet along classical lines." In this way, Blasis was ahead of his time. He took particular interest in some movements considered to be too aggressively virtuosic for the Romantic era of the early 1800s. For example, he initiated the codification of the pirouette, breaking it down into a preparation, turn, and finish.

Death Blasis died in Cernobbio.
