"Anthoine Singlin (1607–1664) was a French Jansenist Catholic priest, best known as a member of the Jansenist community at Port-Royal-des-Champs and as head of the Petites écoles de Port-Royal (set up by his friend Jean du Vergier de Hauranne).
Anthoine Singlin began his priestly career beside Vincent de Paul, at the hospice de la Pitié in Paris. He was then a devoted disciple of Jean du Vergier de Hauranne, abbot of Saint-Cyran and spiritual director of the monastery of Port-Royal. When he was imprisoned in the Bastille on the orders of cardinal Richelieu (from 1638 to 1643), he declared Anthoine Singlin's spiritual training complete and made him his intermediary between prison and the nuns and Solitaires at the monastery." - (Wikipedia (en) 23.12.2020)
