In the context of epigraphy and papyrology, the survival of papyrus records is largely attributed to climatological chance. While papyrus is a fragile material, Egypt’s exceptionally dry climate—specifically its low humidity—prevented the decay that would typically destroy such organic documents in more temperate environments.123

Because of these arid conditions, many papyrus rolls remained protected for centuries, often buried within desert sands or preserved in tombs where they were placed as part of funerary customs, such as the Book of the Dead. This preservation allows scholars to study a vast array of documents, ranging from legal and administrative texts to literary and scientific works, which provide invaluable insights into the ancient Mediterranean world. In contrast to stone or metal inscriptions, which are the primary focus of epigraphy, these perishable papyrus records offer a unique, detailed window into the daily life and history of ancient Egypt.213
