In former times there were four so-called palace prelates (prelati palatini):
The maestro di camera is the real chief chamberlain. His authority extends over all matters concerning the daily personal service of His Holiness. He is the immediate superior of all the chamberlains, both clerical and lay; he has charge of the service of the Anticamera as regards the four acting clerical privy chamberlains; he informs the orderly officer of the Noble, Swiss, and Palace Guards respectively, of the hours of duty for the next day; he summons the privy and honorary lay chamberlains to their period of weekly service, and dismisses them at the end of it. All petitions for audiences are lodged with him, whether they are presented to him immediately or whether they are presented to him (in diplomatic language) mediately, by the Secretary of State. He issues the summonses to audiences, and regulates all occasional, unusual, or unofficial ceremonies, such as the reception of pilgrimages and the like. Being in daily personal touch with the pope, he receives his orders concerning the Anticamera of the next day, and makes arrangements accordingly. As supernumerary Prothonotary Apostolic he is always at the head of this college of prelates, irrespective of the date of his appointment. At papal audiences and on other occasions when the pope sits upon his throne without pontifical vestments, the major domo stands on the right, the maestro di camera on the left, both on the second step of the throne. The extent of this prelate's jurisdiction is limited exclusively to the reception rooms of the pope. He also has some ancient privileges, which may be read of in Humphrey, "Urbs et Orbis".
