In Late Greek, the word prōtokollon referred to the first sheet of a papyrus roll bearing the date of its manufacture. In some instances, it consisted of a flyleaf that was glued to the outside of a manuscript's case and provided a description of its contents. Coming from the Greek prefix prōto- ("first") and the noun kolla ("glue"), prōtokollon gave us our word protocol. In its earliest uses in the 15th century, the word referred to a prologue or preface and also to a record of a document or transaction. In the late 19th century, it began to be used in reference to the etiquette observed by the Head of State of France in ceremonies and relations with other dignitaries. This sense has since extended in meaning to cover any code of proper conduct.
