El filosofo natural Frances Edme Mariotte (1620-1684) introdujo en el siglo XVII un aparato compuesto de un marco de madera con una serie de pendulos alineados en un mismo plano (Mariotte, 1717).
Hacia 1680, Edme Mariotte reproducia el supuesto experimentum crucis y encontraba resultados que le parecian contradecir e incluso refutar a Newton: el haz violeta que lograba aislar arrojaba, tras la segunda refraccion, una imagen en la que se mezclaban los colores rojo y amarillo.
