The codex PP is a in-4° volume, vertical, in a thin parchment. Today, this manuscript has 98 folios, i.e. nearly 45% of the Qur’anic text, dispersed in several libraries in Paris, St. Petersburg, Vatican and London.
As all the other witnesses of the first 2 centuries Higra, it has no date and no localisation. We only know the site where it was preserved, at least at the end of the 19e cent. : the storage of the ‘Amr mosque in Fustat.
Déroche’s dating is based on two major arguments : 1. palaeography and 2. orthography.
Thus, Déroche assumes that the copy of codex PP has been done between 50/ca 670 and 80/ca 700.
