The Chronicle of the Canons Regular of Mount St. Agnes

The place used to be called in the vulgar tongue Mount Nemel and lieth not far from Zwolle, but one may traverse the distance in the space of an hour. Now there were in the State of Zwolle certain faithful men who had been turned wholly to God by Master Gerard Groote. These men had builded them an house, in a suburb belonging to the city, near an ancient Convent of Béguines, and here they served God humbly and with devotion.
