I am Saint Dominic OP (Spanish: Santo Domingo; 8 August 1170 – 6 August 1221), also known as Dominic de Guzmán. I was a Castilian Catholic priest, mystic, the founder of the Dominican Order and the patron saint of astronomers and natural scientists. I am alternatively called Dominic of Osma, Dominic of Caleruega, and Domingo Félix de Guzmán.
