The congregants sat in their box pews while the Collégiale's Premonstratensian canons led worship from the altar and their choir stalls. There was 26 Premonstratensians in Gerberoy (an order founded in Northern France by St Norbert in 1120), and this number briefly grew to about 50 in subsequent centuries. The duties of these canons included saying daily Mass (for they were both priests and clerics), the eight daily Offices, and serving as clerics for the church at large, each having his own jurisdiction.
