J. Henry Middleton, Illuminated Manuscripts in Classical and Mediaeval Times… (1892)
“ The best kinds of papyrus paper are close in texture, with a smooth surface, very pleasant to write upon with a reed pen, and adapted to receive miniature paintings of great refinement and delicacy of touch. To prevent the ink spreading or soaking into the paper, it was as a final process sometimes soaked in size made of fish-bones or gum and water, exactly as modern linen paper is sized. The colour of the papyrus is a pale brown, very pleasant to the eye, and excellent as a background to the painted decorations. ”
