THE QUILL SWIRLED and lunged over the page in a slow but relentless three-steps-forward, two-steps-back sort of process, and finally came to a full stop in a tiny pool of its own ink. Then Louis Phelypeaux, first comte de Pontchartrain, raised the nib; let it hover for an instant, as if gathering his forces; and hurled it backwards along the sentence, tiptoeing over i's, slashing through t's and x's, nearly tripping over an umlaut, building speed and confidence while veering through a slalom-course of acute and grave accents, pirouetting though cedillas and carving vicious snap-turns through circumflexes. It was like watching the world's greatest fencing-master dispatch twenty opponents with a single continuous series of maneuvers.
