This week’s featured purchase for the Vincentiana Collection at DePaul University’s Archives and Special Collections is an early 19th century hand-colored print depicting Vincent de Paul celebrating his first mass. The location of this event has traditionally said to have take place at the Church of Our Lady of Grace in the town of Buzet-sur-Tarn. This is also the town in which Vincent was said to have gathered around him a number of young men for whom he served as a tutor during his time as a student at the University of Toulouse. This print is believed to be part of a series depicting incidents in Vincent’s life.
