Skeat “… in at least three cases and probably in all, in the form of codices " and he theorized that this form of notebook was invented in Rome and then “… must have spread rapidly to the Near East …” In his discussion of one of the earliest pagan parchment codices to survive from Oxyrhynchus in Egypt, Eric Turner seems to challenge Skeat ’ s notion when stating “… its mere existence is evidence that this book form had a prehistory ” and that “ early experiments with this book form may well have taken place outside of Egypt .” Early codices of parchment or papyrus appear to have been widely used as personal notebooks, for instance in recording copies of letters sent ( Cicero Fam.
