Saint Dominic,, also known as Dominic de Guzmán, was a Castilian Catholic priest and the founder of the Dominican Order. He is the patron saint of astronomers and natural scientists, and he and his order are traditionally credited with spreading and popularizing the rosary. He is alternatively called Dominic of Osma, Dominic of Caleruega, and Domingo Félix de Guzmán.

The Order of Preachers, also known as the Dominican Order, is a Catholic mendicant order of pontifical right that was founded in France by a Castilian priest named Dominic de Guzmán. It was approved by Pope Honorius III via the papal bull Religiosam vitam on 22 December 1216. Members of the order, who are referred to as Dominicans, generally display the letters OP after their names, standing for Ordinis Praedicatorum, meaning 'of the Order of Preachers'. Membership in the order includes friars, nuns, active sisters, and lay or secular Dominicans. More recently, there has been a growing number of associates of the religious sisters who are unrelated to the tertiaries.
