Ink

All I could find on what The Book of Deeds of Alexander the Great was written with was ink on parchment. It looks as if only black or brown and red ink were used.  Through research it is my guess that it was probably written using iron gall ink, which was the common ink used in the later medieval ages.  The red ink could have been made in two different ways.  Either vermilion turned red by mixing it with egg whites and gum arabic, or vinegar infused brazilwood chips mixed with gum arabic.
