colossus means

A colossal heroism: order of excess, triumph over formlessness: “For the primitive Greek, colossus does not mean size, but figuration, a little doll could be colossal if it achieved its figuration, if it triumphed over the formlessness. A superior order of excess, a new creationist order of man and of the gods.” (“Homenaje a René Portocarrero,” 1962). To conceive formlessness, according to Lezama, means following the trace of becoming that goes “from a nebula to the cosmos.” More than imposing a form on the formlessness, a sense of finality, we must crown it, capture it without stopping it, and allow it to reach its best sense at the moment it escapes.
