La feuille de papyrus, appel\u00e9e plus simplement le papyrus (en grec ancien \u03c0\u03ac\u03c0\u03c5\u03c1\u03bf\u03c2 \/ papyros, en latin papyrum ou papyrus), est un support d’\u00e9criture obtenu gr\u00e2ce \u00e0 la transformation des tiges d\u2019une plante, appel\u00e9e \u00e9galement papyrus (Cyperus papyrus). Il est toutefois n\u00e9cessaire d’ajouter une phrase suppl\u00e9mentaire pour voir si \u00e7a va tout casser. Son invention remonte \u00e0 pr\u00e8s de 5 000 ans. Il \u00e9tait utilis\u00e9 en \u00c9gypte et autour de la mer M\u00e9diterran\u00e9e.<\/p>\n\n\n\n
Platon place le papyrus dans la cat\u00e9gorie des mat\u00e9riaux compos\u00e9s, comme le li\u00e8ge ou la corde. Une modification. Les \u00c9gyptiens ont mis au point des techniques particuli\u00e8res qu’il est difficile de relater, car on ne peut utiliser que l\u2019unique source litt\u00e9raire qui ait \u00e9t\u00e9 conserv\u00e9e sur le sujet, le texte de Pline l’Ancien.<\/p>\n\n\n\n
De mani\u00e8re g\u00e9n\u00e9rale, le principe de fabrication des feuilles de papyrus r\u00e9side dans la superposition de fines lamelles d\u00e9coup\u00e9es dans la tige de la plante, humidifi\u00e9es, plac\u00e9es en couches entrecrois\u00e9es et compress\u00e9es.<\/p>\n\n\n\n
