first , the dancegirls donning full-length gossamer robes dewed with specks of silvery pearl ... shimmering , being water-falling upon smooth marble , so the girls danced enchantedlyenchanting , evoking , summoning ... boys with simple azure stoles looped around their necks ... becoming sky and clouds to the falling rain ... a prancing and looping that was practiced during the courseback then it was boys alone , girls alone ... each step memorized , but here turning into what none could have foreseen , yet what each so achingly yearned for ... a gracefulness of individuals who , dancing , become group and at the moment of grouping , disperse into communal imaginings .
