Made  of plaster in 2001 and bronze in 2009. "The universe is the space that the artist must conquer", comments Costi. "In the space, the artist must move freely. He must be adaptable and malleable. He must see without resistance". In this sphere of relationships, the artist develops the idea of the dance as an expression of the conquest of space, where bodies are able to move in total freedom. The essential element, the original module of the single dancer, evolves into a pair which dynamic profile of signs leaves the overall vision intact, even while describing the details, characterising the figures in their individuality without releasing one from the other.
