Herolt has been described as "the most prolific, skillful, and honored writer of sermon books in fifteenth-century Europe".
[1][self-published source] He was "one of the leading figures of a new Dominican spirituality in fifteenth-century Germany which emphasized the practical goals of pastoral work over mystical study".
[2] As lector and prior of the Dominican monastery in Nuremberg, Herolt was a colleague of Johannes Nider.
Herolt was also vicar of Nuremberg's Dominican convent, the cloister of St Katharine, which he and Nider reformed in 1428, appointing Gertrud Gwichtmacherin as prioress.
Herolt's Advent, Christmas and New Year sermons to the Nuremberg convent in 1436 - his only work in the German vernacular, Der Rosengart - have recently been translated and published.
