A 1.5. The size of the parchment document

The size of the parchment document depended on the size of the raw skin, which in turn, depending primarily on the species and age of the animal. Due to the high price of parchment, the surface of the parchment was maximised, and the extent of the parchment document often stretch from one of each skin to the other. For large-scale documents, the skin of large adult mammals had to be selected, the surface of which varied to a great degree. In the case of unfavourable environmental conditions, the difference thicknesses and fibre orientations can cause the deformation of the historical records.
