The collaborative performances of dancers and visual artists gave rise to a new and urgent need: a shared language. The artists of the First Canvas, through a process of experimentation and consensus, began to develop a system of recurring symbols, a visual lexicon. Certain colors came to be associated with particular emotional states, specific shapes with abstract concepts. The speed and rhythm of the projected images also took on meaning, creating a kind of visual prosody. This was the First Visual Language, a complex and nuanced system of communication that was entirely independent of the dance, yet perfectly capable of harmonizing with it. It was a language of pure light, a way to convey complex ideas and subtle emotions through the silent poetry of form and color. The invention of this language was a major intellectual and artistic achievement, and it would have a profound and lasting impact on the culture of the Children of the Symbol.
