The Dominican Order, founded in the early 13th century, quickly recognized the power of both liturgy and hagiography in solidifying its collective identity. As the Order expanded across Europe, it sought to establish a shared sense of purpose and belonging among its members.

In the first fifty years of its history, the Dominican Order understood the importance of creating shared experiences and narratives that fostered a sense of unity and purpose. Bernard Gui’s work is a critical part of how the order used hagiography to further that goal. This involved:

  • Standardizing liturgical practices across its various priories and convents.
  • Promoting the veneration of specific saints associated with the Order.
  • Commissioning hagiographical works that celebrated the lives and virtues of these saints.
These efforts culminated in the creation of a distinct Dominican identity, characterized by its commitment to preaching, scholarship, and the defense of the Catholic faith. The Speculum Sanctorale emerged as a key expression of this identity, offering a comprehensive and authoritative collection of saints' lives tailored to the Order's specific needs and values.
