Vincent de Paul only pursued art as it was useful for teaching or assisting in the attainment of spiritual goals. John Rybolt describes and analyzes the two engravings in the original edition of the Common Rules. These constitute the title page and the frontispiece, which are reprinted here. Vincent approved these and they summarize the themes of his teachings. Both convey reverence for the Trinity. The title page also highlights the importance of veneration for the Eucharist and devotion to Mary. The frontispiece shows Jesus teaching or healing, and sending his apostles to continue this work. The importance of imitating Jesus, especially in deeds for others, is emphasized.
