These protocols gave rules for imperial progresses to and from certain churches at Constantinople and the imperial palace, with fixed stations and rules for ritual actions and acclamations from specified participants (the text of acclamations and processional troparia or kontakia, but also heirmoi and stichera are mentioned), among them also ministers, senate members, leaders of the "Blues" and the "Greens" during the hippodrome's horse races who had an important role during court ceremonies. The following chapters (84-95) are taken from a 6th-century manual by Peter the Patrician. They rather describe administrative ceremonies like the appointment of certain functionaries (ch. 84,85), investitures of certain offices (86), the reception of ambassadors and the proclamation of the Western Emperor (87,88), the reception of Persian ambassadors (89,90), Anagorevseis of certain Emperors (91-96), the appointment of the senate's "proedros" (97). The "palace order" prescribes the conveyances required for movement (i.e. on foot, mounted, by boat), as well as the participants’ costumes and acclamations, some of which were debased Latin, which had not been an administrative language for more than three centuries.
