Parchment is animal skin prepared as a smooth, durable surface for writing. It was made from the skins of sheep, goats, or young calves by removing the hair and flesh, treating the skin with absorptive material, stretching and drying it, and smoothing it with powdered pumice. It was used for scrolls and documents.
Paul requested that Timothy bring his parchments. The reference indicates the use of prepared writing material for written documents or scrolls.
The name is connected with Pergamum, where parchment was believed to have first been used. It was widely used in the early Christian period and had replaced papyrus for many scrolls and legal documents.
